About this part

Product Details

When you're working on the top end of your engine, especially for a Big Block Ford, finding Top Dead Center (TDC) precisely is crucial for timing and assembly. This COMP Cams piston stop is a well-built tool designed to help you do just that, without needing to remove the cylinder heads.

It screws directly into the spark plug hole, featuring an 18mm thread specifically for Big Block Ford applications. Once in place, it positively stops the piston at TDC, giving you a solid reference point. This bolt-style stop is a practical solution for ensuring your engine is timed correctly during rebuilds or modifications.
