can i run a 4k spring with stock valve springs? or has anyone ever done this?
yes, set your timing around 16-17* and it won't want to rev past about 3500... you'll be fine
ive free reved mine to 4200 rpm's with stock valve springs. was alot intoxicated and i WOULD NOT recommend this to anyone!!! lol luckly i didnt drop a valve but im sure it was damn close
what are you doubting?? that i did it or that the valve to piston clearance was very close??
so would 40 psi and 3400rpms be ok? with stock springs
