I'm with the intake and carb group. The cam, heads, and compression are all for a low rpm torque engine. But the intake is for a high rpm HP engine. I'd start by switching to a dual plane inake.

The Edelbrock carb is another story. Essentially, it's an updated version of the old Chevy quadrajet carb. By all accounts an excellent carb with good tuning capabilities. But, that's where the problem lies. if you don't know how to tune it properly, it's easy to get it so out of shape that it just won't run right. Find some one who knows how to tune them, or switch to a Holley.

But, that's just my opinion. I could be wrong.
