Mahle MS piston set for a GM 346ci-style build supplies eight forged pistons sized 3.898in bore with a 3.622in stroke and 6.125in connecting rods. Each piston uses a 0.927in pin and a slightly negative dish volume (-4.1cc) to target roughly a 10.2:1 compression; the matched set is intended for accurate, balanced engine assemblies and routine rebuild applications.
