This is the next chapter of the 1969 Camaro we modified in the V8 Speed & Resto Shop with all new Detroit Speed suspension, Forgeline Wheels, Baer Brakes, Toyo Tires, Holley EFI, and more go-fast and handling goodies. Here’s the original forum thread telling that part of the story:

And the video from that experience:

Well, remember how we said that some cars are never finished, and are on a constant evolution to improve? WELL, this ‘69 is back in the shop for some upgrades once again!
This time, the owner wanted to change the personality of the car a bit and move from the angry 540 Big Block Chevy into an LT4 supercharged power plant for a more refined - but still powerful - driving experience.
We started the engine removal process by protecting the car with a Badass Fender Cover… which should be called a nose cone, to be honest.

We measured the spacing on the hood to fenders and valance for reference, and then removed the hood. All the engine fluids were drained, exhaust was disconnected, wiring harnesses disconnected… all the usual items required for engine removal. Out came the big Chevy engine.

Tyler experiences DejaVu on this car, recalling the first time the engine came out of the car before the big suspension overhaul!

The Chevrolet Performance LT4 V8 engine arrived on a pallet from another shop, where it had been painted black and upfitted with an underdrive pulley system to generate more supercharger boost pressure. The dry sump oil system tank is also visible on the pallet in this shot.

These generate around 640 horsepower and 630 lb. ft. of torque, but the mods on this one will ensure more oomph than that.

The LT4 features direct-injection, and it comes in the Z06 Corvette in regular production trim.
Here the Drive Junky LT4 front accessory system is visible.

SWEET! Plenty of belt wrap one those pulleys. Did you bigger on the top pully as well as the bottom? Bottom I think I read 9.20, what is the top?

I believe the upper pulley is stock... pretty darn small from the factory. I imagine a smaller pulley would also be harder to keep traction for the belt with such small surface contact.

Time for a quick test-fit of the LT4.
https://lh3.googleusercontent.com/-ukNoOsx2Awc/Wj2MjH63LmI/AAAAAAACtGY/30h2mAgYh9ES5ZvFCkhL1sF05uzkvpWUQCHMYBhgL/s1600/1969%2BCamaro%2BLA_12-20-17_0025.JPG
We had recently installed a new Centerforce DYAD clutch and flywheel on our 540 big block Chevy engine but we wanted to run a Centerforce DYAD clutch with the LT engine as well. However, the LT flywheel would be different. Rather than install the new flywheel with a used clutch and split up the set, we elected to obtain a new flywheel and DYAD DS clutch from Centerforce for the LT engine, and offer the matched clutch and flywheel from the big block for sale.
https://webinjected.blob.core.windows.net/images/store/centerforce/ctf-04614844-1_lg.jpg
The Centerforce DYAD DS is a thing of mechanical beauty. The machined flywheel is nearly too nice to hide inside a bellhousing!

BUT… it wouldn’t do much good on the bench! ARP hardware holds it to the LT4 crank.
https://lh3.googleusercontent.com/-2IECKef-TGc/Wj2Mm5RJP8I/AAAAAAACtGY/HjkP42Qex5g-Lz5c-GkLYn-SB_3_nTnAACHMYBhgL/s1600/1969%2BCamaro%2BLA_12-20-17_0032.JPG
You’ll notice some pink / red dots on the components… these are alignment markings provided by Centerforce. This system was balanced at the factory, and they are kind enough to place the parts in the box all ready to go. However, if you seperate them, you can realign the parts using the dots to during installation so they remain in balance.
The DYAD part… the 11” clutch disc and the “floater” dual disc assembly. Centerforce claims these will hang on to up to 1300 lb. ft. of torque while still being able to drive comfortably. We’ve found the driveablility claim to be true in several high-hp cars, including this one with the 540. These units provide predictable “grab” with smooth engagement and a pedal you can live with.

The pressure plate and clutch plates mounted to the LT4 with ARP studs. The alignment tool is still in place in this shot. The pink dots correspond with the dot on the flywheel. The cad-plated ring is the front half of the explosion-proof scattershield.

We lowered the LT4 into the nose of the Camaro and shot a quick video. Excuse the quality, this is from a V8TV “Minute To Winnit Live” video we streamed on our Facebook page.

Pics of the fit and some new surprises next time!
Beautiful car.
What are your plans for the heat exchanger?

We'll be using a C&R unit designed to work with the LT4 and Vintage Air.

Beautiful car.
What are your plans for the heat exchanger?
This one will get a C&R LT Heat Exchanger. The LT heat exchanger has inlet and discharge on the driver's side of the car vs the LSA on the passenger side. This marries up nicely with the intercooler manifold on the top of the engine which discharges on the driver's side.
Regards,
Larry
There are numerous connections off the back of the LT4 that require some space to access and make them look clean, as well as for serviceability.
https://lh3.googleusercontent.com/-1PhwO96YclM/Wl6E5GdLz4I/AAAAAAACy7U/6ifPYCW3fi09pnFEOPSLHT1NSGkB43lgwCHMYBhgL/s1600/1969%2BCamaro%2BLA_01-03-18_0005.JPG
The V8 crew lowered the engine into the bay just to get a visual of how things were going to fit. This car had a smoothed firewall, and A/C bulkhead fittings down on the passenger side. The motor mounts had not yet been chosen, this was just to get a bird’s eye view of any potential challenges.
https://lh3.googleusercontent.com/-Yhp3cWs5aMo/Wnh2VbRTCNI/AAAAAAAC0qo/h2WcJFrGIeYHThylgVYuQPEY6sruv4sEACHMYBhgL/s1600/1969_Camaro_LA_2017.12.20z1.jpg
It was obvious that there would be some clearance issues on the back side of engine as the assembly moved closer to the transmission.

The engine was lifted out, and the firewall was examined. At this point, the team noticed that the existing firewall was showing some cracking bodywork and would require a fix and repaint regardless.
https://lh3.googleusercontent.com/-Y61BN121dgE/Wj2M2dapdrI/AAAAAAACtGk/CDUU8caFLNYuaT658h89ndE1LjUGwsUngCHMYBhgL/s1600/1969%2BCamaro%2BLA_12-22-17_0060.JPG
The decision was made to modify the firewall to better accommodate the new engine and fix the surface issues. In order to do this, the front sheetmetal was to be removed.
The team carefully measured and recorded the gaps, spacing, and fitment of the panels and the alignment so that everything would go back together properly.

Here you can see the bruised firewall. We decided to investigate further.

Lots of cracks and filler are lurking below…

Putting the engine back in place on Dirty Dingo mounts in the Detroit Speed subframe, we could see the clearance from the head to firewall was a bight tight.

The accessory drive seemed to fit well, even with the increased diameter crank pulley.

There’s room for the A/C compressor as well.

But the decision was made to do some work on the firewall to repair the damage and make a bit more room for the engine, as well as to clean up the A/C bulkhead fitting holes.
The Camaro was moved to the metal fabrication shop where the new firewall would be created.
Once the heater block off panel was removed, it became obvious that this car was originally painted blue. It was also obvious that because of the cracks and previous finish work, the heater block off panel was holding water and rusting the bottom of the firewall. Water literally ran out when we removed the panel.

The main piece seems to fit pretty well. Next, the tunnel portion is marked for an extension piece on the firewall. This will allow more clearance for the LT4.

Thanks guys! The A/C appears to fit so far.
Doom, don't think of it that way... another person got the BBC from this car, so it lives on!
The LT4 runs a dry sump oiling system, meaning it does not have traditional oil pan holding the engine oil supply. Instead, the oil is stored in a seperate tank outside the engine and is pumped through the engine. The benefit is more consistent oil delivery during high speed turns and increased oil cooling and capacity. Also, the pump is more efficient and easier to service than a traditional oil pump.
The down side is the need for complex plumbing and an oil reservoir tank under the hood. Also, it can be challenging to bring the engine oil up to operating temperature in daily-driving conditions thanks to the higher capacity and cooling effects of remote tanks and plumbing.
Locating the tank can be tricky, as one must consider packaging under the hood. In a race car, you ideally want the tank to be “inside” the wheelbase of the car where you can place it to compliment the vehicle’s balance. However, packaging compromises can dictate otherwise.
In our case, we elected to install the custom Peterson Fluid Systems tank in the forward part of the passenger fender.

Superchargers create a lot of heat, so the cooling system needs to be effective. The LT4 will be keeping its cool thanks to a C&R Racing radiator and supercharger heat exchanger. These are bred from C&R’s F1 racing program and offer many innovations for performance and strength.
The heat exchanger is designed for the Camaro’s grille opening size.

C&R builds these tube cores to withstand pressure of 100 psi in F1 racing, a pressure they won’t ever see in a street car like this, but they withstand “ballooning” and potential cracking and bursting like rolled tubes.

They’ve also added reinforcements to the structure to keep the tanks and cores from separating and leaking.

Thank you! There have been some part hang-ups along the way or we'd be further down the road at this point. But you know how it goes, you cannot predict the speed of suppliers and service providers. Overall progress is going well. Thanks for the feedback!

What's important to note about the heat exchanger for the LT4, the inlet/discharge are on the driver's side vs. the passenger side for the LSA.

Thanks!! After I asked the question, I realized he had a LT4. Yeah, I called C&R this morning and asked what's the differences in LT vs LS heat exchangers and where the line connections are essentially is the only difference. C&R said if you have a water-cooled supercharger, either one would work as long as you didn't mind which side the lines routed to.
Things are coming together on the LT4 swap.

There goes the warranty. LOL When do we get to hear the "varooom, varooom" sounds?
This was a take-out engine from another car, so there were no warranty concerns from the start. The GM warranty is pretty good on crate engines, and we are an approved shop for those installs, and have been through the process with them. It went very smoothly. This one had some miles on it when it arrived, but outside of a few sensor issues, it seems healthy.
Vroom vroom to come shortly!
Thanks!
At this point, the decision was made to install the later version of the LT4 supercharger hat, which will accommodate water / methanol injection jets from Nitrous Express.
Water / Methanol injection is a great tool to reduce the intake charge temperature, allow for more aggressive ignition timing, and therefore increase the power output of the engine.
The system uses basically the same solenoid system as a nitrous oxide kit, but this time, it’s spraying a water / methanol blend under much lower pressure. A reservoir tank and pump are needed, as well as some form of controller to make it work.
Here, the jets are plumbed into the new hat and the solenoids are mounted. Nitrous Express provides this service, which came out great.

The new hat didn’t match our desired color scheme, so it was cleaned, scuffed, and masked for some new color.

Looking good!

The liquid side of the alcohol injection system required a pump and a reservoir, so we built a tank to fit in the driver side rear quarter panel out of stainless.

Next, the team wired up the T56 Magnum transmission using a Bowler All In One harness. This is a handy piece that incorporates all the connections required on a T56 for safe operation into one harness.
http://v8tvshow.com/V8TV_2/images/RestoGalleries/1969_Camaro_LA/6/1969_Camaro_LA_2018-06-05.0210.JPG
From Bowler:
“The All-in-One harness solution for the Tremec T-56 Magnum transmission comes equipped with all the connections pre-wired into one harness for a simple installation and ease of use. The small epoxy sealed controller is mounted to the VSS output using the existing bolt, and once the unit is powered up you will be able to connect via Bluetooth to your Apple or Android smartphone using our free app. The app will give you the ability to customize the input and output settings for each feature to ensure proper operation in your vehicle. The All-in-One harness eliminates the need for any additional equipment to operate the reverse lock out or generate the correct speedometer signals coming from your Tremec T-56 Magnum. This All-in-One harness solution is the perfect finishing touch for any Tremec T-56 Magnum conversion, and the only harness you will ever need.”

Very Nice!!
The LT4 was finally ready to fire, and the crew double checked all the connections, hoses, fittings, and added some fuel. The calibration is from the GM Performance ECM with some adjustments made to accomodate the Drive Junky pulleys, exhaust, and custom air intake. We use HP Tuners software and worked with Mike Norris on the calibration to get the car in a driving state.

Initial drives we casual, as we datalogged the ECM and would beam it over to Norris for analysis. We’ve tuned many an LS, but this was LT4 #1, and we trust Mike to be a great resource on these kinds of projects.

Driving the car is a blast… when the power comes on, you’d better be ready! It shreds tires at will. Two V8 Team members Trevor and Tyler took the car on a 600 mile shakedown run to the Holley LS Fest in Bowling Green, KY, with no major issues, save for a power steering leak at the rack. Overall, it was a great ride for them. Our freinds at Forgeline were kind enough to host the car for the weekend.

However, we’re not at the finish line yet. It turns out that the car has an issue with the throttle during upshifts where the RPM climbs a bit after the throttle has been closed. It seems this is a “thing” with LT4 swaps, and we’re working with GM and a few others to land on a solution… more on that shortly!

We discuss our fix for the LT4's RPM issue in the latest episode of V8 Radio. You can jump to the 43 minute mark to get right to it (but you really want to listen to the whole show, right?)
** We don't reveal the fix, but we do discuss how we approach these going forward. It will make sense if you listen.
