[CobraV81396]

I made the cam change (Ford racing hydraulic) and it runs fairly good (11.81 quarter mile), however, I was thinking of going with a slightly hotter cam (260 degree with 640 lift solid flat tappet - less inertia and milder ramp than the solid roller) now. Good compromise and good performance from what I hear.

I was also pointed towards Manley valve springs as a solution too (heard that Comp Cam springs are not very good). I know a couple guys running an even hotter solid roller (672 lift) for racing. May expect problems with this cam though (but 700hp!).
