PROFORM 66789 Pushrod Length Checker for Small Block Chevy with 3/8-Inch Rocker Studs

The PROFORM 66789 Pushrod Length Checker is designed to help determine the correct pushrod length for Small Block Chevy engines using 3/8-inch rocker studs. Proper pushrod length supports accurate rocker arm geometry, reliable valve-train operation, and consistent engine performance during assembly or valvetrain upgrades. This adjustable checking tool provides a practical way to verify fitment before ordering permanent pushrods.
The checker is intended for engine builders, professional technicians, and performance enthusiasts working on Small Block Chevy applications. Use it during cylinder head, camshaft, rocker arm, or valve-train installation to evaluate pushrod requirements with the selected components. Establishing the correct length can help reduce premature wear and promote stable valve motion throughout the engine’s operating range.
The PROFORM 66789 is supplied as an individual pushrod length checker and is intended for use with 3/8-inch rocker studs. Its straightforward design makes it convenient for checking valve-train geometry during mock-up and final component selection. Always follow the engine and component manufacturer’s setup procedures, and confirm measurements for the specific combination of block, cylinder heads, rocker arms, lifters, and valves.
