I have just recently purchased the Edelbrock CH4B aluminum intake. Basically it is an aluminum version of the stock intake. I wanted to be sure that my air grabber fit properly on my air cleaner.

The CH4B is taller than stock , I used to recommend it ASSuMEing it was the same as stock because it was NHRA approved.

The ONLY intake that is the same as a stock cast iron is the original M1 dual plane .
