Your cart is empty.These High Energy Die Cast Aluminum Roller Rocker Arms for Chevy V8 265-400 applications are perfect for street and moderate race use. With a 3/8" stud diameter and 1.5 ratio, the die cast, larger-than-stock body of the rocker arms is made of aluminum for superior strength with light overall weight. High Energy Die Cast Aluminum Roller Rocker Arms from COMP Cams are an affordable option that feature a die cast, aluminum body with a needle bearing fulcrum and roller tip. Designed to be stiffer and more durable, these cost effective rocker arms are capable of providing added valve lift while withstanding the rigors of a performance application. Their specially engineered fulcrum and roller tip create far less friction than sliding factory models to lower oil temperatures, thus improving both response and horsepower. Snap rings are used to hold the trunion and bearings locked in place

Installed these 7/16 mount 1.6 ratio arms on my mild cam SBC 350. They made a noticeable difference in increased engine RPM top end, throttle response and power through the whole band. They also made my mild cam wake a up a little adding more duration and lift. Excellent set of roller rocker arms!

Excellent Rocker Arms. Strong, reliable and quiet. Need to make sure you have clearance with your valve covers.

I have a '79 Corvette that I am restoring the engine is not stock. While driving it all of a sudden I could feel a loss of power so I drove home and started checking for the problem. I had a dead cylinder. I was getting good spark and the plug was fine so I pulled the valve cover. When I bought the car it had Pro-Form Roller Rockers and that was the problem the intake rocker on the dead cylinder had broken. I decided to pull the heads and have valve job done just make to make sure everything was good on the top end. The valve guides where worn so that may have had something to do with broken rocker in all fairness to Pro-Form. I ordered a set of these and they are much better quality and beefier. I installed these and followed Comp's instructions on adjusting them and haven't had any problems and my Vette is a beast again.
