Dissapointing performance

Yeah guys go easy probably a bit of language disconnect going on like he said... I think he is willing to try the carb and exhaust (right?), I think that's what you need as well. And do a compression test at least to see what your cranking compression is, that will tell how good the performance will be at lower RPM in general.

I know you think 2" exhaust isn't hurting much but it's probably becoming a restriction before the engine starts making peak TORQUE, let alone HP with that cam. If you increase the flow with 2 1/2" pipes it will probably increase torque slightly even down to 2500 RPM and it will just pull harder and harder from there on up. Try unhooking the headers and running them open, I bet it screams and/or the carb runs super lean lol.
