ok i have an 83 fox with 1.7 crane roller rockers can i run the trick flow stage 2 without any piston to valve clearance?
Total valve lift has nothing to do with possible PtV clearance issues. Stage2 cam uses an X-303 intake lobe so clearance on the intake side shouldn't be a problem even with stock heads based on what I have experienced. Exhaust clearance needs to be checked. Checking for PtV and correcting if required, is a procedure that needs to be done anytime you upgrade the camshaft anyway. LUK

ok well we just installed a trickflow stage 2 cam with 1.6rr in the car and had no problems but with the 1.7rr i am not sure if we can do that with no ptv clearance problems. i am not sure of the formula that you can use to check it and not sure what difference the 1.7 vs the 1.6
Joel, can you explain that to me? I do not understand how lift has nothing to do with clearance... I understand the overlap period is the crucial point for clearance issues but how does a .600" lift cam not come closer than a .300" lift cam?
The only reason I didn't buy the TFS Stage 2 cam is I thought it was too much lift for my flat tops, I would still like to get one myself, if you don't have to flycut the pistons.
Thanks,
Scott
