Hey Jim, all I was thinking was how to keep the fuel and air as cool as possible. By moving the fuel line as far away from the engine, insulating the filter, steel braiding the fuel line, insulating the bottom of the filter housing, running a 1/2 in phenolic carb spacer, a Holley heat shield. And built a dual inlet cold air system for cooler air. The biggest improvement turns out to be is more timing, absolutely no detonation or pinging on 93 octane. And more seat of the pants power on full, hard acceleration. Air at filter housing, no matter how hot the engine bay is seems to be around 80 to 90 degrees. Isn’t showroom stock, but looks good and runs incredible.
