I just realised today that my block has a 0 deck height, I think the machine shop 0 decked it, but didn't tell me. I had .025 which I figured everything out, I would have 8.35:1 with my pistion/ head combo. well, I figured everything with a 0 deck height today and 8.81:1 is the comp ratio, still ok for 8 PSI of turbo boost, probably right where I need to be, because of the turbo I have, will be most efficent right around 8 PSI. so my new HP numbers figuring desktop dyno 2000 are 324 HP @ 6k and 283 Ft/Lb @ 6k. seems about right to me.
the pistions are 2.3L HSC ( Tempo/ Taurus ) pistions, so they might be the cause of the decreased deck height, but IDK, the head surface shure looks milled.
