Product Details
This is the COMP Cams Guide Plate FS/CS 3/8in Flat A, part number 4839-1. It's a two-piece, adjustable guide plate designed to keep your pushrods properly aligned in Chevrolet Small Block engines (265-400 cubic inches) and Ford 289-351W engines. This is especially important if you're working on the top end of these engines, as it ensures the pushrods move smoothly and don't bind against the cylinder head. The hardened steel construction with a black oxide coating means it's built to last and resist wear.
This particular guide plate is designed for engines using 7/16" rocker studs and 3/8" pushrods. Its adjustable nature allows for precise alignment, which is crucial for consistent valve train operation. Having the pushrods track true helps maintain proper geometry and can contribute to better performance and longevity of your engine components.
