I have a 350 bored .020 over.
Smogger heads 8.5 comp ratio
Speed Pro cam 442/465
Holley street dominator intake
Edelbrock 650 cfm carb
3.27 rear end
TH350 with shift kit
Soon longtube headers w/ true dual exhaust.
I am not sure if I am over cammed or under cammed or just right.
It just feels a little bogged down out of the hole, I have thought about putting a stall on it and seeing if that helps.

 

My car was exhibiting similar problems. Turned out to be my timing. Have you check your timing?

 

Yeah I know the timing is fine, but I just think I may have gone with the wrong cam. My car feels like a slug off the line.
