"If it don't go...polish it!" --Old SStroker (2009)

 

How do i go about doing that. Alu. roller rockers ive heard make an extra 15-20 hp. How much power does upgraded stock free up?

 

Stock GM or Stock GM with upgraded trunions.

I can help you with the polished WP as well.

Thanks,

You have been listening to the wrong people. Actually, using aluminum roller rockers in place of stock LS rockers may cost you power. The are heavier and have more weight over the valve which is bad, and they are not as stiff (they are more "flexible") which is also not good. It takes more spring to control them which is also not good.

Upgrading the bearings on stockers is for increased durability, not for more power. Many, many folks run OEM stockers on high hp high rpm engines without the upgrade. That's why I listed them first.

There is an upside to brightly anodized aluminum roller rockers: they look bitchin' to the ricers when you pop off your rocker covers.
