a friend of mine asked what would happen if you used roller lifters on a flat tappet cam and i couldn't come up with an answer for him.. i've never strayed from roller on roller, flat on flat, so i have no idea if there's an issue.. would anything happen to the cam or lifters?
I don't even know if it would run, the lobes are designed differently
More important is why would you do that ?
i wouldn't, i stick with roller/roller and flat/flat.. i'd much rather stick with running what i know.. but a buddy of mine asked because he wants to put a cam he bought off me in his motor and run roller lifters
Don't try it.
Tell him its a bad idea :D
roller lobes are more round for the rollers to roll on and flat have more of a peak and will not work with rollers..
Yeah no.
yeah, i've noticed that when i sat my HO roller cam next to the blue racer when i laid them side by side, but didn't really know if it made a difference.. thanks, i'll pass the word on
