I am rebuilding an '04 Raptor top end and decided to do some cam tests. But, before I waste time and effort, I wanted to know if anyone has ran a 4x4 Grizzly 660 cam in a Raptor and if so, what kind of performance was achieved. As you can probably tell, I am aiming for brutal, low-end grunt.

 

The hot cheap upgrade for the grizz was running an oem raptor cam. It's my guess you'd be better off testing aftermarket grizzly cams instead of the oem.
