Thread: Anyone Using COMP Cams Pro Magnum Roller Rocker Arms??

Tweet

I just picked these rocker arms up to go on GM Performance Fast Burn heads. Are any of you running these, and what do you think of them? Price wise they were equivalent to aluminum, but stated that they were 5% less weight at the valve. Let me know if any of you have them, and if they're working good for you. I probably should have asked this prior to puchasing them, but I'm hoping for some positive feedback. Thanks.....

I have in the past, no problems with them. They were on a street engine that never went past 7200 (rev limiter) and held up great. As with installing any new rocker arm, make sure your pushrod length is correct..... The majority of problems blamed on rockers are actually an improper length pushrod issue.....

i have used both the 1.5 and the 1.6 pro magnum rollers on my sbc,, excellent product, i have used the 1.6 for 3 years now with absolutely no problem.. when i build an engine for friends etc i always reccomend them

Thanks for the feedback. They are advertised as an excellent product, but I just wanted to make sure they'd perform the way I hoped.

dave is rigth .you will find that many companys rockers are not all the same rocker arm geometry. bigger roller tips. trunions and push rod cups not in the same location. if you look at 4 companys rollers rockers they may all be diferent in geomertry . so make sure the pushrod are right .but i have used them they work fine
