COMP Cams Guide Plate Olds 5/16

What you get here is a single, flat, one-piece guide plate from COMP Cams, designed specifically for Oldsmobile 350-455 cubic inch V8 engines. This guide plate is built to work with 5/16" diameter pushrods and 5/16" rocker studs, which is a common setup for these classic V8s. It's a necessary component when you're dealing with the higher spring pressures and lift found in performance engine builds, helping to keep your pushrods aligned correctly under stress.

This guide plate is hardened and finished with a black oxide coating, giving it good durability for the demanding environment inside an engine. COMP Cams used precise manufacturing techniques to ensure an accurate fit, meaning it should install without needing any machine work, especially when paired with their #4542-16 studs. The design features rounded contact points where the pushrod sits, which helps reduce wear.

This part fits a wide range of vehicles, including many Buick, Cadillac, Chevrolet, and Oldsmobile models from the mid-60s through the late 80s, such as the Oldsmobile Cutlass Supreme, Buick Electra, and Chevrolet Caprice. It's a straightforward component that plays a key role in the valvetrain's stability.
