About This Product
MCS +.020" oversize cast piston for late 1978-1984 1340cc Shovelhead motors. Standard 8.5:1 compression ratio. Each piston includes wristpin and clips. Order rings separately. Cast pistons expand predictably. This intermediate oversize suits 1340cc Shovelhead rebuilds where the first oversize is insufficient. A qualified mechanic should verify component compatibility before installation. Standard break-in procedures ensure correct ring seating and long engine life.
Manufacturer part number: 504510.
