There are several schools of thought about how a cowl induction hood functions best. One is what 565 and 83montess have done where they are pulling air in from the cowl to feed the carb. I think that a cowl works best for giving the heat somewhere to go. You might think that means your carb will be feeding on the hot air from the engine compartment but you'll find just the opposite. It will be feeding on the fresh air that is displacing the air that is escaping out the cowl.Meaning instead of air filter sucking hot engine heat.... having filter seal against raised cowl and utilizing the pressurized air at the base of the windshield? If so pics would be great!
If you can appreciate, the car in my avatar makes a TON of engine heat when it's working hard and the air coming out of the cowl will actually heat the windshield. We tried to run with a stock hood and the engine bay temps are just too high - to the point that I have to start pulling timing when city driving.
