SEMA 2013: C&R Racing Makes LSA Swaps Easy for ’69 Camaros

A new C&R Racing water-to-air heat exchanger for GM’s LSA engine will make late-model engine swaps into the 1969 Camaro much easier.

“You have to drill only one hole in the stock core support to install this heat exchanger,” says Paul Hammond of C&R.

The topside bracket of the heat exchanger is secured to the hood-latch bracket while the bottom bracket bolts to the core support using existing holes and the single new drilling. C&R worked closely with Vintage Air to ensure that the heat exchanger and the A/C condenser have no clearance issues.

C&R uses a soft-mount system for increased durability, and AN plumbing can be ordered in place of the standard 3/4-inch hose fittings.

“We were both competing for the same real estate,” notes Hammond. “The whole key to key to the project was making it work with air conditioning.”

C&R has adapted a factory-style mounting strategy with rubber bushings.

Additional vehicle applications for the C&R heat exchanger are under development.

“Aluminum expands and contracts at different rates than the steel mount locations,” explains Hammond. “If it’s a rigid mount, then there’s a possibility it could tear itself apart. It’s our version of what the OE’s are doing.”

The heat exchanger is part of a closed-loop cooling system for the LSA intercooler. The C&R heat exchanger works with both Cadillac and Camaro intercoolers. It comes with standard 3/4-inch hose fittings but C&R offers AN plumbing options.

“The core itself is modeled after the ZR1 Corvette model (supercharged LS9 engine), so we’re shooting for high-horsepower applications,” says Hammond. “It’s all-aluminum construction with 5052 alloy. It’ll shine up nice if the owners wants to polish it, or you can paint or powder-coat it.”

C&R is working on new brackets to expand the vehicle application for the heat exchanger.
