Piston and ring kit 73.50mm bore or .094" oversize dish top work out to approx 9.95:1 unless heavily machined bores.
Gives a great torquey engine with those extra ccs.
Chrome or cast rings USA brand Hastings Quality pistons.
TIP: with this bore size we believe it is worth drilling the 2 extra stud holes. We can supply an ARP bolt for the thermostat end c-aht281.
