Compression Ratio: 10.3:1 with 52cc Heads

This Piston Kit is based off the tried and true Wiseco K0079X2 Piston that we have had extreme amounts of succeess with. We change from a -6cc dish to a -3cc flat top for a tad more compression, add lateral gas ports for better top ring seal and upgrade the wrist pins to a .200" Wall Tool Steel for extra rigidity. This kit is an excellent choice for any 4.6L 4V combo making 600 - 1300 WHP. Don't let the lightweight strutted forging fool you, these pistons are extremely strong in design and this exact part number has been as fast as 4.5X @ 155+ to the 1/8th mile.
