Pushrod Length Checker BBC Intake & Exhaust

The MANLEY Pushrod Length Checker for Big Block Chevy Intake & Exhaust is an essential precision tool for any serious engine builder or mechanic performing valve train work on BBC applications. If you're assembling or modifying a big block Chevy engine—whether for street performance, racing, or restoration—getting pushrod length exactly right is non-negotiable. Too short and you'll starve valve train geometry; too long and you risk valve float and catastrophic engine damage.

This checker eliminates guesswork and ensures your intake and exhaust pushrods are cut to specification before final assembly. MANLEY's pushrod length checker is engineered with precision machining to deliver repeatable, accurate measurements across both intake and exhaust valve configurations on Big Block Chevy platforms. The design allows you to verify pushrod length while the cylinder head is mounted and the rocker arm geometry is indexed—mimicking real operating conditions—so your measurements reflect actual clearances under load.

Compact and lightweight at just 0.2 lbs, it fits easily into any mechanic's toolbox and requires no special setup or calibration. The hardened steel construction resists wear across hundreds of builds, and the intuitive design works with standard pushrods and aftermarket options alike. Engine builders, machine shops, and high-performance enthusiasts rely on this tool whenever porting heads, upgrading rocker ratios, or fitting custom cam profiles that alter pushrod angles.
