Alright guys I finally got my new engine done and up and running for a couple days now. The new combo is a TrickFlow Street Heat upper and lower, stock GT-40Ps, Trick Flow Stage 1 Cam (221/225,499/510) Hedman LTs, and at the moment stock T-body and MAF Untuned until I have those and Aeromotive Adj. regulator. I have had trouble finding the right amount of timing and fuel press. to make this thing more happy than it currently is. Just curious what fuel press. you guys have run that worked well, and for you guys with GT-40 heads what degree of timing worked well for ya? Also what heat range plugs would you guys suggest? Thanks beforehand for any input.
