Lunati has 14 different LS1 and LS6 rotating assemblies available.The Lunati engine assemblies are made with the finest Lunati engine components, including a Lunati Pro-Series crankshaft, Lunati Pro-Billet connecting rods, Lunati forged pistons, rings, bearings, and piston pins.

If a turbo or blower is to be used, they recommend 8.5 CR with pump gas. For racing and race fuel you can move to 12.5 CR for maximum performance. The pistons and rings come in 0.005" oversize to accommodate honing to clean up the cylinders. The top ring is a 1.5 mm moly plasma pre gapped ring, second ring is 1.5 mm cast-iron reverse-twist, and the oil ring is 3 mm three-piece. The assembly is internally balanced and the reluctor ring is installed. All this, and with your choice of up to 408 cubic inches! It doesn't get any better.

We are offering discounts on all of the Lunati stroker kits and cams that we carry. Orders can be placed online or by calling 1-877-4-TBYRNE.
