Hey guys,

I am having some trouble with my acceleration. It seems as though the engine is not advancing well from ~ 0 - 3000 RPM. To the point where if I'm at a stop light and stomp on it, it'll die. Above 3000 it seems to work fine. It's a 71 with a 350. It has the stock HEI setup with a Edelbrock 600 performer on a conversion plate on the stock manifold. It also has the stock fuel pump. I've taken the distributer off and the vacuum advance seems to be working as well as the mechanical advance. The weights were free and the springs seemed good. It idles a little rough, but not bad, and the timing seems appropriate too.

Any Ideas....Help!

Thanks

Drew
