The Ultra Pro Magnum Roller Rocker Arms for Chevy V8 265-400 applications not only live up to the lofty standards of the original Pro Magnums, but they also take stud mount rocker performance, stability and value to a whole new level. These rocker arms feature a 7/16 stud diameter and 1.52 ratio. The 8650 chromemoly material and arched, web-like design deliver increased strength and rigidity while still reducing the moment of inertia and optimizing the dynamic balance. A unique black oxide exterior finish helps prevent corrosion and increases durability. Featuring oversized trunions, precision-sorted needle bearings and hardened roller tips for the ultimate in performance and dependability. Optimized retainer and valve spring clearances allow for use of most diameter springs, retainers and +.050 locks without clearance or fitment issues.
I was really looking forward to these rocker arms, but one arrived defective and I had to contact customer service. They replaced it quickly, but it was a hassle to deal with. Performance is good though!

Best choice for my rebuild!
These Comp Cams rocker arms are fantastic! The 1.52 ratio gave my SBC just the boost it needed. They’re well-made and really perform under pressure. Would definitely buy again!

Solid but had a hiccup
I like the quality of these rocker arms, but the shipping took a bit longer than expected. Other than that, they work great on my SBC and have really enhanced my throttle response!

Decent product, some minor issues
The rocker arms are good but not without issues. One of the arms didn't fit as smoothly as the others, which made setup a bit tricky. Performance is nice once you get past that though.
