Mike,the 440 liked your 850..and Brad's,and Russ' 950HP even more...at least at the track! Brad,Gary Jacob's(Jake68)chassis dyno is a DynoJet. Rob,the GTX usually 60's in the 1.52-1.56 range. Do you guys agree with the 80-100 hp increase from the head work? I believe,if I can get decent traction..and run 1.49-1.50's,I could hit my 10.8-10.9 goal. BTW..the engine dyno at St. Clair Engine,where I'll be running it,is a Stuska..which is a division of Power Test Inc. Anybody here know how accurate these are? Thanks! Randy
