: My original motor in my mav which was mildly built saw 7000 once :( and then it was basically a boat anchor as it broke the block and shattered a piston when it struck the valve and that piston musta been in a thousand pieces. My current .30 over 302 has the roller valvetrain and has seen 7000 a couple times when i miss a gear. 4 gears you got to love um lol.
: : Most 302's will NEVER see beyond 5000-5500 rpm...6500 is MORE than enough...

: : : are only good to like 6500rpm. The spring tension required for the valves at that rpm is too high and will compress the hydraulic lifters. Thats what got me off of my roller lifter plans...
