Autotec 1000524 Ford 351 Cleveland 393 Stroker Pistons

Autotec 1000524 pistons are built for Ford 351C Cleveland 393 stroker combinations using a 4.030" bore, 3.850" stroke and 6.000" rod. The -11.7cc dish gives useful compression control compared with flat top pistons, especially where chamber size, cam timing, fuel quality and street use all need to be considered together.

The 1.260" compression height suits the listed 393 Cleveland stroker combination. Final deck height, gasket thickness, chamber volume and piston-to-valve clearance still need to be checked by the engine builder during mock-up. Do not assume final compression or clearance from piston specs alone, because that is how engines become expensive paperweights.
