Generation IV External Engine - roller rocker arms

Anybody recommend a quality brand for my LS3? And how much HP do they generally offer vs. Stock to rocker arms? Thanks. @

I'd just get a reunion upgrade bud, what cam are you thinking of throwing in?

A reunion upgrade? What is that? The cam is a
.632 lift predator cam(comp cans grind) from XTREME HP in Texas

418 stroked forged internals 575 rwhp N/A.

I think he ment a trunion upgrade. The rollers in the stock rockers. FWIW, im using stock rockers with a .620 lift cam with a trunion upgrade. Many people are. Eric L

Hmmm I was leaning toward the theory of the rollers creating more power based on faster rotating parts. What does a trunking upgrade provide? Thanks

Sorry trunion?

The roller fulcrom part in the stock rocker. You press out the stock non caged bearings, and press in the comp cams caged roller bearings. Do some searches on here about rockers, you will find some good write ups. Eric L

Thanks

P.S. That Valiant is old school Badass! :thumbs up:

Old school badass, with an LS swap, lol. Eric L

Just check your sweep pattern if you plan on using the stockers. While they are a great option esp with the trunion upgrade they arn't always best in higher lift applications.

I'm still using the factory rockers with .617/.624 lift:D

Thats good information to know. Never really thought about it before. Ill have to check that on assy. Eric L

Jessel Rockers are hard to beat, but expensive. Yella Terra is very good and they are reasonable
