Info

For Big Block Chevy. Just slip it over a 7/16" rocker arm stud to instantly tell how much longer or shorter the pushrods need to be.

  • Long valves, milled heads, cut blocks, small base circle camshafts all move rocker geometry far from optimum
  • Correct length pushrods keep rockers centered on the valve tip and reduce stem and guide wear
  • Checker tells the engine builder instantly what length pushrod is required

Notes

This is a very simple tool to use:

  1. Rotate lifter to cam base circle and slide the tool over the rocker stud.
  2. One of the ears on either side of the tool will rest on either the valve tip or the pushrod.
  3. If the tool rests on the valve tip, you will measure the gap left between the pushrod and the end of the tool. This distance will be added to the existing pushrod length for the new length needed for correct geometry.
  4. If the tool rests on the pushrod, and there is a gap between the tool and the valve tip, you will subtract the distance from the existing pushrod length for correct geometry.
  5. Works great with a pushrod length checking tool.
