Mahle MS pistons for BBC 505ci engines come as a set of eight with a 4.350in bore, 4.25in stroke and a .990in wrist pin. With 6.385in rods and a 43.0cc crown volume yielding about a 13.2:1 compression ratio, the set supports high‑compression big‑block builds where matched bore, stroke and combustion volume are required for correct final compression and piston-to-chamber fit.
