Tim 2 4's look nice under any cobra hood. However you have to watch out that you don't get George's red light bug. It's in KitCar mag. The guy does great motor work and still redlights with an auto.
I have a stelling air filter on my throttle body, but the throttle body is 1" flater than a carb. Go with the K&N air filters also. I can put a 1 " spacer under my throttle body and still have an 1" to play. Rick Lake
