The Performer RPM is about 5.8" tall from the end rails of the block to the top of the carb flange. Indy's Tunnel Ram for the B-engine is 10" tall.
I want to run fuel injection, and I think the throttle body is a little shorter than a carb.
Also I want to put a Hemi scoop on. So the air filter could poke up into the scoop a little.
