Default Need Camshaft Advice
I have 98 formula that is fully bolt on and runs 11.40's stock internal. My motor has 128K miles. Im thinkn about doing a cam soon but if i put one in, i wanted to go big. Would you guys recommend putting a cam in with this many miles? If, yes could i put a magicstick4 or G5X4 in without flycutting? Any replies would be nice, thanks Sam

I agree, i think as long as the valvetrain is solid the bottom end will do its job up to 6500rpm. I wont need much more than that anyways.

Your car seems like a very likely candidate for a TRex camshaft.
