**** 360 Piston Options ****
summit is messing with U, the w405cp under notes: recessed head .070" deep, and U are adding 10cc for a "dome" just cuz they say +10cc when U should be subtracting 10cc for a dish. what was the compression height on those 340 pistons, probably the 1.73 from the 1972-3 8.5:1
