thanks for the reply. I have a question. I bought a 306 short block w/ forged pistons and swapped my top end onto it.(professionally done) Once i broke in the motor i started getitng on it and it didnt seem very fast. I brought it to a tuning shop and they believed the "meter" might have gone or the cam degree was off. They changed the cam degree from 13 to 10 degrees. It was faster now but still not like the first motor by any chance. At this time i can pull a 14.03 (gtech) out of it. With my old motor i ran a 12.65 at the track. Some guy was talking about vacuum 19psi to 15psi i believe. I dont know how to check that. If you can help it would be appreciated.
P.S. Stayed dead even with a 2001 6 speed trans am. non ram air
3 days ago. Twice in a row.
