What size pushrods and rocker studs do these guide plates work with?

These COMP Cams guide plates are specifically designed for 3/8 inch diameter pushrods and 7/16 inch rocker studs. This sizing is common in many performance Chevrolet Big Block applications.

Are these guide plates suitable for stock engines?

While they fit a range of Chevrolet Big Block engines, these guide plates are particularly necessary for performance engines running high lift camshafts and increased spring pressures. They help maintain proper pushrod alignment under these demanding conditions.

What does the black oxide finish do?

The black oxide finish on these guide plates provides a layer of protection against corrosion and wear. Combined with the hardened steel construction, it helps ensure the durability of the component in the engine environment.

Product Details

COMP Cams is a well-known name in the performance engine world, especially for their valvetrain components. If you're building a performance Chevrolet Big Block engine, you'll want to pay attention to how your pushrods are guided. These 1-piece guide plates are designed to keep your 3/8" diameter pushrods properly aligned, which is crucial when you're running higher spring pressures and lift in a performance setup.

These guide plates are raised and made from hardened steel with a black oxide finish for durability. They feature rounded contact points for the pushrods and exact stud placement, which helps ensure a smooth operation. COMP Cams used stereo lithography techniques to get an accurate fit, meaning they should install without much fuss on your Chevrolet 396-to-454 c.i.d. Big Block engine, provided you're using 7/16" rocker studs. They come as a full set, ready to go into your build.

This guide plate set fits a wide range of Chevrolet vehicles, including popular models like the 1965-1973 Chevelle, 1967-1972 Camaro, and 1966-1974 Corvette, among many others. They are a necessary component for anyone looking to get the most out of their performance engine build.
