..... I am still thinking valves hit pistons with Your drag race rpms.

So.... are saying that IF the engine had some valve "float" at my "drag race" 5,500 RPMs, the floating valve(s) would contact the top of the piston?  :smack:

This interesting because I believe the 261C cam profile has one of the higher overlap (6.2 degrees) of the cams I have recorded or tested.

QUESTION:  Could excessive camshaft overlap  (significantly greater than a stock cam profile) be more likely to cause valve float, and potentially cause valve to piston interference?

Gnarls.  :inthedark:
