Tfs Stage 1 To X-303 Back To Tfs Stage 1

[Stroked408]

straight up is always a good starting point,my concern is your compression ratio with those heads,those AFR 185's are some big heads and they need air in them moving around,quick question when you switched the tranny out did you switch the computer out also? If you did not you are going to notice small pinging at the track tomorrow,in the upper rpm range because your computer is going to want to pull timing out thinking it is time to shift the tranny,maybe,maybe not if it was me I would get call up engine shop like Cam Motion,BES Racing,Fox Lake,USA Racing Engines and Glidden Racing Engines and shell out the bucks for a custom grind job,remember TFS makes killer cylinder heads,you don't see Comp Cams building cylinder heads do you? just my 2 pennies good luck on the track tomorrow but watch your plugs and listen for detonation at upper rpm's
