Once the firewall was cured, the mechanic shop took over with the final install of all the goodies.



The Detroit Speed subframe and suspension was cleaned up amd the new firewall protected as the LT4 was set in place.









Looking pretty good up there.

The team begins to install the various systems on the car and LT4.

Engine wiring is routed low through the bulkhead plate made in our metal shop.






The Ultimate Headers are exhaust artwork, with cast stainless flanges and stainless tubes. The ARP hardware squeezes MLS gaskets, and the headers utilize 1 ⅞” stainless tubes. These are Jet-Hot coated satin black.



Detroit Speed subframe leaves plenty of room for headers.



They sure are pretty.

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.



Pins on the bottom of the heat exchanger locate it in the mount, which uses rubber bushings to protect against vibration harm.



Mounting “shelf” with rubber bushings.



A rubber padded top mount slips between the stock Camaro support and vertical bracing.



Note the 4 mounting tabs and screws, those are for mounting a Vintage Air condenser core to the front of the heat exchanger. These are provided by C&R.

On the back side, the radiator is mounted to the core support.



A high fin and tube per inch count increases surface area for better cooling, and the tubes are actually extruded for strength. These are shots of a cutaway:



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.



The driver side incorporates an engine oil cooler, and the twin Spal fans are visible here.



Passenger side connections for engine coolant. Aluminum bracketry bolts to the stock Camaro radiator support locations.



Here, the Vintage Air A/C condenser core has been added to the front of the heat exchanger.

Things are coming together on the LT4 swap.



Supercharger coolant pump is mounted low on the subframe.



One fender in place, power module shown in foreground. The supercharger is removed to install some fittings.



Inside in LT4 supercharger. “Bricks” on sides are heat exchanger / intercooler coils.
