Solid Roller Lifter Selection

Well, I can certainly see where the bigger wheel is desirable. Probably does a bit better in longevity. It also doesn’t mean I’ll have read running a smaller wheel but there are limitations right?

Anybody have any data?


There you go. Any power increase is almost nothing. But the durability goes way up. Not even close. There is a reason why the GM clowns all use .904 (or bigger lifters) and it’s not to run a .750 wheel. They could do that on an .842 lifter. It’s about making them live.

Of course, if you are .650 or less lift (ball park number) and keep the engine under 6500 (Amy unwritten 65/65 rule) you can get away with a .750 wheel.

For the money saved it’s just not worth it to use the .750 wheel.
