Good info for sure....

Im wondering if you have run the HP hyd rollers in a big inch street/strip Hemi and what did you find/learn ? Or even in engines that traditionally have valvetrain issues?

Some say that the Hemi's valvetrain is too heavy and the pushrod angles/pushrod seat in the hyd roller make it an unstable valvetrain not able to rpm easily.

Care to share?






Most of the stuff I do is BBC, but some of that is .371" stem stuff and it is heavy. Morel does use the same body on the high rpm stuff for Chevy/Ford/Mopar. In more than not the Mopar block will need to be bushed for it to work. The street stuff is just fine.

The .903" pro series lifter will benefit from a shorter pushrod due to the tall seat location in the lifter.

Most of the Mopar stuff I have cammed has been solid roller stuff.
