00:01 On this episode of Hot Rod Garage,
00:03 the Chev-Hell sees some boost.
00:04 (engine revving)
00:07 (tires screeching)
00:10 (upbeat rock music)
00:29 - Welcome back to Hot Rod Garage, presented by Lincoln Tech.
00:32 We're here today with Lucky's Chevelle.
00:34 It's a '66 Chevelle he calls the Chev-Hell.
00:36 It's one of my favorite driving hot rods.
00:38 This thing was super reliable, handled awesome,
00:41 stopped great, six liter LS truck motor
00:44 with a T-56, super fun car.
00:46 And you've used it up.
00:47 - I've worn out the transmission,
00:49 worn out the motor, worn out everything,
00:51 broke suspension parts, so this is a complete redo.
00:54 - And this car has been all over.
00:55 Power tour a couple times.
00:56 - Couple times.
00:57 - Yeah, we've taken it to the drag strip a couple times.
00:59 We've done dyno runs.
01:00 - To and from Vegas, yeah.
01:01 - Everything.
01:02 Lucky basically drove this thing into the ground.
01:05 - To the ground.
01:05 - Into the ground.
01:06 You've already upgraded the suspension.
01:07 - Yep.
01:08 - Motor and trans is out,
01:09 and it's time to make some horsepower.
01:11 - That's right, we're gonna do the Magnuson supercharger
01:13 and some AFR heads.
01:14 - Some cylinder heads and a Roots supercharger.
01:17 - Yes, very happy man.
01:18 I was having a hard time containing myself.
01:20 - You look excited.
01:21 - I am.
01:22 - All right, let's get started.
01:23 (upbeat rock music)
01:28 - So here it is, the six liter Addy or Chevelle.
01:31 - Yes, it is.
01:31 - This thing made 415 wheel horsepower.
01:34 And what did you do to it to make that kind of power?
01:35 - Well, this thing was a DOD motor,
01:37 displacement on demand.
01:37 It used to have a gadgetry that went on the top right here
01:40 that would shut off pistons and cruise.
01:42 Took all that off, changed the cam,
01:44 timing cover, oil pump.
01:45 I put ARP head bolts in it and some new head gaskets.
01:48 And we have taken turns beating the crap out of it
01:50 ever since.
01:51 - We sure have.
01:52 We had a ton of fun at 400 horsepower.
01:54 How much are we gonna have at 600 or 700 horsepower?
01:56 - Yeah, I don't know.
01:57 The answer is lots.
01:58 So let's get these heads off and put the other ones on.
02:00 - All right, let's go.
02:01 (upbeat rock music)
02:04 - So when we were putting in the head studs,
02:18 everything went in fine except for the short ones at the top.
02:21 So we have the tap.
02:22 We're gonna just chase all the threads
02:24 with a nice clean little tap.
02:25 And I'm taping it up so that none of the metal shavings
02:28 go into the motor.
02:30 Join us, won't you?
02:31 - I don't really know if I should recommend this
02:35 or just have a disclaimer that this is not something
02:38 I would probably do myself.
02:40 - But cars with muscle--
02:41 - If you have more than two minutes to spare--
02:43 - Engines with muscle.
02:44 - Do it by hand.
02:46 The LS9 is a multi-layer gasket,
02:48 so it's gonna seal a little bit better.
02:50 And since this will have increased cylinder pressure
02:52 from all that airflow and the boost of the supercharger,
02:54 these should help out.
02:55 So what are these AFR heads?
03:00 - These are the 72cc.
03:02 - And the intake valve is a 2.080,
03:05 and the exhaust valve is a 1.6.
03:07 233.3cc intake port flows up to 328 CFM.
03:12 - So we got the studs in, we got the washers all installed.
03:16 They give you an assembly lube that you just put
03:19 on the bottom side of the nut.
03:21 It stops metal from metal, basically.
03:23 It stops it from galling and still allows you
03:25 to have an accurate torque specification.
03:28 - So it's time to torque down these AFR heads
03:34 with the ARP studs.
03:35 Now, every time you get a fastener kit,
03:36 there's going to be specific torque instructions.
03:39 These guys are nice enough to give us a cool procedure,
03:42 as well as the torque value.
03:43 Every car has a pattern.
03:45 Every manufacturer specs one out.
03:47 And it's just to basically start from the inside
03:49 and sort of work your way out to make sure
03:51 that the head lays down flat.
03:53 - Okay, so we just got done torquing all the heads down.
03:56 That all worked out great.
03:57 Cleaned up all the push rods, checked the measurements.
03:59 They all check out just fine.
04:00 I'm going to drop them all in,
04:01 and then Tony's going to come in
04:02 with the rocker arm assembly,
04:03 and we're getting a little bit closer every minute.
04:07 - Every engine's different.
04:07 LS has separate pedestals,
04:10 so you want to make sure that every one is lined up
04:12 close enough to get on top of the push rod.
04:15 And we're going to spin the motor over as we torque it in
04:17 to make sure that the cam is on the base circle
04:19 of each rocker as we tighten it down.
04:22 - So I just got done taking off the truck accessory drive
04:24 and the lower harmonic balancer.
04:26 This is the Corvette harmonic balancer.
04:28 This will move all the accessories, belts, drive,
04:31 and everything closer to the engine block,
04:32 which will allow us to put a heat exchanger
04:35 between the core support and the front of the engine.
04:37 We're going to have that much room.
04:38 - It's going to take a lot of power from the cranks.
04:41 You have to drive that supercharger,
04:43 and these things tend to spin,
04:44 especially on modern engines, which aren't keyed.
04:47 They're just slip fit.
04:48 So there's a cool solution from Magnuson.
04:50 And what we're going to do is use this little fixture,
04:52 drill a place to drive two pins in between
04:55 the crankshaft snout and the dampener.
04:58 So now that we have these holes drilled,
04:59 when we install these pins,
05:00 there's no way that one will be able to spin
05:02 without the other one.
05:03 - Next stop, the water pump.
05:11 Called Rock Auto.
05:13 Pretty sure we ordered the right stuff.
05:15 (drill whirring)
05:18 There it is.
05:23 Rock Auto.
05:25 - I feel like a horse is going to come galloping in
05:36 when I do that.
05:37 - So now it's time to put the valley pan on for real.
05:42 Lucky put some new O-rings in the bottom
05:44 we were waiting on.
05:45 Here it goes.
05:46 Great job, everybody.
05:49 Ready for the fun part?
05:56 - I'm ready, buddy.
05:57 I've been ready.
05:58 - The crowd's going crazy.
05:59 - Let's make it look really heavy.
06:02 - Act like it's all heavy.
06:03 - Man, all right.
06:04 - One. - Wait, wait, wait, wait.
06:05 - Two.
06:06 - Perfect.
06:12 So we've got the Magnuson supercharger
06:13 laid onto Lucky 6-0.
06:15 Now we're just going to bolt it down
06:17 and then we've got a couple different things to figure out.
06:19 But it went right into place.
06:20 Belt alignment looks good.
06:21 We're well on our way.
06:22 So we just spent like 25 minutes
06:27 goofing around with different accessory spacers,
06:29 trying to get everything all figured out.
06:30 - It was more like 45.
06:32 - It was a long time.
06:33 Water pump on, off, on, off, on, off.
06:35 Short, mid-length, long, blah, blah, blah, blah.
06:37 Anyway, we've got it all figured out.
06:38 Turns out we don't have the stuff we need.
06:40 Let's throw this motor in the car
06:41 while we have some stuff overnight.
06:43 - Yes, yes. - Let's do it.
06:45 - We've decided to put the clutch and flywheel on
06:52 before we put the engine in, which I like doing anyway,
06:54 but also it's going to be way easier for you guys to see.
06:57 - Okay, so this is the clutch by Hayes.
06:59 It's a dual disc clutch.
07:00 This is the pressure plate.
07:02 These are the discs.
07:05 - Yeah, and it's full metallic with a sprung hub.
07:08 So it's like race plus street.
07:10 - Best of both.
07:11 - Race plus street?
07:12 - Yeah, it's good.
07:13 - Is that even legal?
07:15 So I have to disassemble the whole thing
07:16 to install the flywheel.
07:18 Then I have to reassemble everything,
07:19 obviously, underneath the car and so on and so forth.
07:22 And here we are.
07:23 It's an aluminum flywheel with a steel gear
07:27 and a clutch surface riveted to it.
07:29 I love this thing.
07:30 (drill whirring)
07:33 (upbeat music)
07:35 - You're good, you're good.
07:56 - I'm going down slow, this is my car.
07:59 Watch your digits.
08:01 - Completely untrustworthy with this machinery right here.
08:04 - You're good.
08:05 - Look at that.
08:11 - Lucky's got his T56 rebuilt and upgraded Transzilla.
08:15 And since there's a fresh clutch,
08:16 we are going to do the measurement again
08:19 to see exactly where the clutch fingers sit.
08:21 We use this information to figure out how many spaces
08:23 we want to put behind the throwout bearing
08:25 so we can get just under a quarter inch of space.
08:27 We've got the trans and the transmission jack.
08:29 It's going up into the car.
08:30 We've lowered the back end of the engine down
08:32 to get the most access possible
08:33 and hopefully it goes right in.
08:35 (upbeat music)
08:37 You have to get both discs perfectly aligned.
08:41 So it's really tough to get these in.
08:43 Input shaft is brand new,
08:44 so it's even a little bit tougher than a well-worn setup.
08:48 - It's literally twice as hard.
08:49 - Yeah, it's pretty tough.
08:51 But we got it all lined up just right
08:53 and it slid close enough that we can get bolts in it.
08:54 So we're in good shape.
08:56 - Where else is it going to fit while it's in the air?
08:58 - We'll do headers, exhaust.
09:00 - For starting on the starter motor?
09:01 - Yeah.
09:02 - Waiting on accessories.
09:03 Oh, here they are.
09:04 - That's like magic.
09:04 - Look at that.
09:05 - What was that?
09:06 That's crazy.
09:07 - These are Hooker Blackhearts made for an LS and a Chevelle.
09:10 - These are very complicated to install.
09:12 Allow me to demonstrate.
09:14 Done.
09:14 - Yeah, mine's close too.
09:16 - Dude, seriously, mine is done.
09:18 - There it is.
09:20 (laughing)
09:21 - Do you see the welds on there?
09:23 - That's a very nice piece.
09:25 I've spent hours putting headers in.
09:26 - Yeah, I've spent hours putting headers on
09:28 and then got all done and they drug on the ground.
09:30 - Yeah.
09:31 - These are tucked nicely.
09:31 - The idea that we didn't have to jack the motor up
09:33 or take anything off is kind of amazing.
09:36 Lucky's throwing in the starter motor
09:38 and I am going to put the drive shift in this thing.
09:40 We're going to keep working under the car.
09:42 There it is.
09:48 - So I went over and opened up the Blackheart box
09:50 of the three inch exhaust that the guys at Holley
09:53 took it upon themselves to send me.
09:56 - All right, so let's try it like this.
09:57 - Let's try it.
09:58 - I think this is right.
09:59 (metal clanging)
10:02 - The header on that side is just a little bit higher.
10:09 I had the same issue before.
10:10 - It's not helping.
10:14 - That's because you weigh like 90 pounds.
10:16 So we've run into a little bit of interference
10:18 with Lucky's homemade trans cross member in this pipe.
10:21 It's no big deal.
10:22 Exhaust pipe is up into the cross member a little bit.
10:24 We'll figure something out.
10:26 (metal clanging)
10:29 - No mercy.
10:32 - That looks sweet.
10:35 - That should do it.
10:36 - Okay, here we go.
10:39 Hold on, careful.
10:40 Little more to the left.
10:41 Easy, careful, easy.
10:44 - Cheese and rice.
10:46 - We'll get that side on.
10:47 - Yes.
10:50 Cool.
10:53 - It's a nice exhaust.
10:54 - Three inch.
10:56 (engine revving)
10:59 - So even though this Holley Blackheart exhaust system
11:19 comes complete with everything to get all the way
11:21 over the rear axle and out the back of the car
11:23 where you don't smell anything,
11:25 unfortunately I got an aftermarket rear differential
11:27 in here and the housing's bigger than stock.
11:29 So we're gonna put some turn downs just before the axle
11:32 and then I'll modify the over the axle tubes later
11:36 and install them.
11:37 - That's a muffler hanger.
11:38 We've got this new inlet snout.
11:43 We changed this to push the throttle body out.
11:45 - Inlet snout?
11:46 - Yeah, that's your high school nickname?
11:48 - My, yeah, that's my street name.
11:50 Lucky wasn't weird enough.
11:52 Okay, so the short bracket finally showed up
11:54 for us to use the Corvette accessory drive
11:57 and I'm getting ready to install it right now.
11:58 Join me, won't you?
11:59 Hopefully the last time this water pump goes on.
12:07 Just taking a little gap out of these things.
12:20 (upbeat music)
12:22 Okay, hold it, go around here, go around here,
12:34 all around this one.
12:36 We're just using a piece of scrap wire
12:39 to get the routing exactly how we want it.
12:41 We're gonna just mark this piece of wire or cut it.
12:43 So now we know exactly how long our belt needs to be.
12:46 - Before the pre-tensioner's loaded,
12:48 so it needs to be an inch shorter than that, at least.
12:51 - I usually get a size above and a size below
12:54 and then I go back to the parts store like two more times.
12:57 - Yeah.
12:58 - All right, so these are our previous mistakes.
13:03 - By ours, you mean roadkill.
13:04 - I think we can all take claim for this.
13:07 I'm gonna just-- - No way.
13:09 - We've got a belt.
13:10 This one's 127 inches long.
13:13 There's not a whole lot of options in this size category.
13:16 - There's two.
13:17 - Yeah, that's two, we'll see.
13:18 Down.
13:20 - This goes back up here.
13:22 - And then you're gonna go, yeah, right, this, exactly.
13:25 - Yeah, that might work.
13:27 - Oh yeah, let go.
13:27 Yeah, we just need to dial it down a little bit,
13:31 but this'll work.
13:32 So we got some of these from Holley.
13:34 It's their new finned valve cover
13:35 and we painted them black and they look radical.
13:38 - Let's see.
13:39 Look at that.
13:40 (upbeat music)
13:45 (drill whirring)
13:48 - It fits, it's weird.
13:56 So originally, the way the car was set up,
13:59 they had the radiator inside the course port,
14:01 which is stock, standard procedure,
14:04 and the AC condenser on the outside here
14:06 where the heat exchanger is now.
14:08 I modified some brackets and made the AC condenser
14:11 bolt to the front of the radiator
14:13 and then made a couple of spacers
14:14 to put the whole thing on the inside.
14:16 And I'm surprised it actually fits.
14:20 I mean, yeah, I meant for it to work like that.
14:23 It's how I roll.
14:24 - I'm changing over to a three bar map sensor.
14:27 This is an earlier GM style,
14:28 but dudes have been using these on race cars
14:30 for a million years.
14:31 I'm just gonna have to change the connector
14:33 and run a boost reference line to it.
14:36 One tip, when you mount these things,
14:37 you wanna put them like this
14:38 with the vacuum source pointed up.
14:41 That way they won't fill with oil or anything
14:42 and they seem to read better that way.
14:44 Okay, so I just got done mounting the coolant pump.
14:49 It actually pumps fluid from the heat exchanger in the front
14:52 to the intercooler under the supercharger.
14:54 Here's Tony with your Lincoln Tech Tip
14:55 to tell you exactly what that does.
14:57 - Welcome back to another Lincoln Tech Tip.
15:06 Today we're gonna talk about the different types
15:07 of intercoolers and how they work.
15:09 There are two main types of intercoolers,
15:11 air to air and air to water.
15:13 Now air to air uses outside air
15:15 to cool the charged air in your system.
15:18 That means that the heat exchange happens
15:20 when the hot air in your charge pipes
15:21 is cooled by air running across an intercooler.
15:24 Now there are some pros and cons
15:25 to running an air to air system.
15:27 The pros are it doesn't take any power to run it,
15:30 there's no water involved so there's no chance of leaks,
15:32 and as long as there's good, clean air flow
15:34 to the intercooler core, there will be no heat soak,
15:36 which is when an intercooler loses its ability to cool
15:39 and temperatures continue to climb and climb.
15:41 The cons of an air to air intercooler system
15:43 are that the overall efficiency is limited
15:45 by both the outside ambient air temperature
15:47 flowing across the core and where that intercooler core
15:50 is mounted in the car.
15:51 Another thing you have to consider
15:52 is that the intercooler core must be mounted
15:55 somewhere that sees fresh air,
15:56 so your packaging options are pretty limited.
15:58 So an air to water system like we have on Lucky's car
16:01 is quite different.
16:02 The heat exchange that's happening here
16:03 is between water and air.
16:05 Basically there is one single heat exchanger
16:08 that takes the heated air from your turbo
16:10 or your supercharger system and it is going to run it
16:12 through an intercooler that's full of cold water,
16:15 cooling down the intake charge
16:16 and letting your engine make more power.
16:18 Now that hot air that's been heated from that charge
16:20 is pumped to a second heat exchanger
16:23 that sits in the front of your car,
16:25 is gonna see cold, fresh air cool that water down
16:27 and send it back up into the intercooler.
16:30 There are pros and cons to an air to water system,
16:32 the pros being that it's super efficient
16:34 and it's gonna make a lot of power
16:36 and because of all the small different parts
16:38 don't need to necessarily be mounted anywhere specific,
16:40 you have a lot more freedom with how you put it together.
16:42 Cons being that there's a lot more moving parts,
16:45 so it's really complex, there's more points for failure
16:47 and it's more expensive.
16:48 As well as because where the intercooler is placed,
16:51 it is more prone to becoming heat soaked
16:52 which basically negates the entire thing.
16:55 So now that you guys are experts on air to water
16:57 and air to air intercooler systems,
16:59 you can use your packaging options,
17:01 your money you have to spend
17:03 and the kind of driving you're gonna do
17:04 to make a decision on which intercooler system
17:06 is right for you.
17:07 - Lincoln Tech can teach you
17:08 how to have a career working with cars.
17:10 See LincolnTech.edu.
17:12 - I'm gonna install this Holley
17:18 105 millimeter throttle body.
17:20 - What, they didn't make a bigger one?
17:21 - I don't think anybody makes a bigger one.
17:23 - The computer makes it open and close
17:25 and bypass some air to basically control the idle.
17:29 That's why they call it an idle air control valve.
17:32 - This has to go to dyno tomorrow,
17:33 but as you can see we're really moving along.
17:35 Cooling system is done,
17:37 supercharger's on, most of the wiring is done.
17:40 Lucky's gotta bring his computer in
17:41 so that we can set it up for the new map sensor
17:43 and injectors, fire it up
17:44 and then get someone way more qualified than us
17:46 to properly tune it.
17:47 So it's the morning on our last day.
17:55 We've been here a few days hustling hard,
17:57 but we're not quite done yet
17:58 and the car has to go to dyno in a few hours.
18:01 - Where do you think this goes?
18:03 - Extra to me.
18:04 (upbeat music)
18:07 This is actually the sub harness
18:12 that comes with the coolant pump.
18:15 It circulates the fluid through the heat exchanger
18:17 and the intercooler.
18:18 It is pre-wired, pre-terminated, pre-put together,
18:21 it's fused and relayed and it is a simple hookup.
18:25 - So I've extended the throttle position sensor wire
18:28 and the idle air control wire,
18:30 plugging those in and we're just about ready
18:32 to fire this thing up.
18:33 What's left Lucky?
18:34 - Ah, the stuff in that one place and that thing.
18:37 - Oh, perfect.
18:38 - The throttle body used to be here.
18:40 So the throttle cable was only this long
18:42 and now the throttle body is up here.
18:44 So the throttle cable is this long.
18:46 This, is that on camera?
18:48 This long.
18:49 But luckily, Holley makes a great little plate
18:51 that bolts right on, holds everything.
18:53 - Moment of freedom right here.
18:56 - Yeah, sure runs quiet.
18:58 It's got to be more whistle.
18:59 - I know, I thought we'd hear it, crazy.
19:01 - Basically, the engine computer is gonna take in
19:04 a bunch of inputs like crank and cam position sensor
19:07 that tells it where the engine is
19:09 and how fast it's spinning,
19:10 throttle position, how much the throttle's open,
19:12 map sensor, stuff like that.
19:14 And then we should be able to get it fired up.
19:16 Okay, go ahead and give me some gas.
19:18 - Offset it to one, or well, let's see what it reads.
19:22 - Let's see what it does.
19:23 - You done playing friggin', what are you playing there?
19:25 - Contra.
19:27 - Here we go.
19:30 (engine revving)
19:32 - So basically, we didn't break anything, right?
19:39 - I don't think so.
19:40 It's rough, but we have a pretty badass tuner friend
19:46 that's gonna fix that.
19:47 - And his name is Sean at Church's Dino Tune.
19:50 - His name's Sean Church.
19:52 - Is it Sean Church?
19:53 - Yeah.
19:53 - Can I get a witness?
19:55 - He's gonna exorcise these demons, you know what I'm saying?
19:57 (upbeat music)
20:00 - We just arrived with Lucky Chevelle
20:13 at Church's Automotive Testing.
20:15 They use a Dynapack style dino.
20:17 These are mobile, small units that bolt to the drive hub
20:21 and read the power, more or less, at the wheels.
20:23 And our buddy Sean is gonna make that thing run awesome.
20:26 It's time to make a whole bunch of power.
20:28 (engine revving)
20:32 So Sean just got done making another pull with the Chevelle.
20:46 We got over 550 horse at the rear wheel,
20:48 over 600 foot pounds of torque,
20:50 which is just astronomical compared to what it used to do.
20:53 We ran out of gas at higher RPM,
20:55 it started to drop off,
20:56 which means we need to replace the fuel pump,
20:58 which means there's more ponies in there.
21:00 Other than that, I am stoked.
21:01 I am super stoked.
21:02 I wanna take this thing out on the road and drive it around.
21:04 - That's what I'm saying, let's go.
21:06 - I didn't know he was standing right there.
21:07 - Time to go.
21:09 Let's party.
21:09 Hey, you know when I said we're supposed to break it in
21:17 150 miles?
21:18 - Yeah.
21:19 - I lied.
21:20 (engine revving)
21:25 - Push me back.
21:26 (laughing)
21:29 - Let's see how she does.
21:30 Woo!
21:35 It sounds cool.
21:39 - It does.
21:40 - Take a tired out old six liter truck motor,
21:43 bolt on some AFR heads,
21:45 and a supercharger,
21:46 and it is bad ass.
21:48 Yeah, this thing screams, huh?
21:52 - Yeah.
21:53 (laughing)
21:54 - You wanna get into a fight?
21:55 That's where you go.
21:56 - Yeah, this thing's looking pretty tough.
21:58 And they're already tired of our (beep)
22:00 I can tell you that much.
22:01 Oh boy.
22:06 Points right there.
22:08 Side note, who is still using car alarms?
22:11 (laughing)
22:12 - I'm so fortunate they have this closed course right here.
22:15 - Yeah.
22:16 Woo!
22:23 - She's got a little something in there.
22:25 - Yeah, she got some pepper.
22:26 Man, we're out here raising hell in the streets.
