Push Rod Length Checker BBC 7/16in Studs

The PROFORM Push Rod Length Checker for 7/16in Rocker Studs BBC (Big Block Chevrolet) is an essential precision tool specifically designed for engine builders and performance mechanics who demand accuracy when assembling or rebuilding BBC cylinder heads. This tool is crucial for ensuring proper valve train geometry, which directly impacts engine performance.

The checker eliminates guesswork by providing a quick, repeatable method to verify the correct push rod length before final engine assembly. It allows users to assemble a test configuration on the cylinder head, measure the relationship between the rocker arm and push rod, and calculate the exact length required. PROFORM's engineering ensures that the checking surfaces are precisely machined to eliminate measurement error, which is critical when tolerances are measured in thousandths of an inch.

This tool is indispensable for anyone performing street or competition BBC builds, whether you're assembling a first-gen small-block upgrade or a dedicated big-block stroker engine. Professional shops, experienced DIY rebuilders, and performance enthusiasts will find this tool invaluable for achieving optimal valve lift and timing accuracy in their engine builds.
