Hood to carb clearance

gnicholson · 07-30-2020, 05:01 PM

Got a new 532 installed in my 70chevelle. With the 4inch cowl induction hood I have 2 inches of clearance between the hood and the flange of the carburetor. Gen consensus is that 4inches is minimum before airflow robbing turbulence becomes an issue. An aero scoop is prob the best performance wise but even with a lot of surgery to make it smaller they still don't look right on the car in my opinion. They make a Sunoco style cowl induction hood that's raised in the middle and then tapers back towards the windshield. Does anybody have any idea what I should do with this thing
