Roller tip vs full roller rocker?

[txaggie]

Howdy all!

I picked up this set of 1.7 full roller crane rockers for a steal. Anyone have any experience with them?

Any benefit to these over roller tip comps?

The benefit would be less friction and more range of motion before binding.

Are they worth it? Yes - if you have a built up motor. If you have a stock motor they would work fine but aren’t really worth it.

Also, Crane is/was a great brand. Iirc, the company dried up after being bought by Holley.

Engine at the machine shop now. Howard hydraulic roller and lifter cam setup, matching Howard double springs, .030 small dome piston, Valve job, small oval heads.

Definitely use them!

One of the benefits of a roller cam is the ability to use more aggressive profiles, roller tip rockers may not necessarily be able to keep up.

I had the Crane gold rockers on my old 454 with a .600” roller cam, they were great.
