Smallblock 6 pac

That's true, I see big block setups all the time. Not so much the smallblocks, I have a good set of ported J heads. Vacuum leaks galore with the aluminum intake. It's an old setup on a new motor, #6 has a 1" crack on the plenum. A good cast dual plane might be an option, and keep the 550 Edelbrock.
At this point I just want to fix it and forget it.
