We used an Afco Ford Lightning intercooler, and made brackets to hang it from the stock rad cradle. I have extra brackets if you are interested or need to go this route. I can post pics later. We mounted the CTS-V intercooler pump on the driver side inner fender by the rad cradle, and the reservoir at the firewall.
I used a Magnuson C5 part in my '68 RS. It requires modification for mounting but it's about as big a liquid-to-air heat exchanger that can be fitted without changing out the hood latch support.
C &R racing is currently developing a heat exchanger/ ac condenser combo for first gen camaros, I know because one will be adapted to fit my Chevy 2 project.
