Got to test out the pulley.. 7.7 was my best 1/8th mile. My previous best with the 65 was 7.8 only difference is I was running the tcu tune which helped a lot. I definetly need the belt wrap kit and will get that done this week, then install my manifolds and get some better times.
Informative blurb, when I went from my Code 3 65 mm to a 178 and Needswings manifolds my AFR's went from 11.8 at redline to 13. If you don't retune, at least run 100 at the track. I ran at 13 to 13.5 at the 1/2 mile and for a few weeks WITH 100 octane with no ill results. Expect to be around 13 AFR.
