The Mahle MS piston set for small-block Ford 392ci with altered rod length is an eight-piece matched kit intended for high-compression SBF builds. It’s sized for a 4.030 in bore and a 3.850 in stroke to produce the listed 392–393 cid while using a longer 6.000 in rod to alter deck geometry. Each piston is 4.030 x 1.275CH with a 6.000 in rod, 0.927 in pin, -3cc crown volume and a 11.6:1 compression ratio.
