The Lunati LS1 stroker kit uses a 3.900" bore and a 4.000" stroke to achieve 383 cubic inches. Pistons are Lunati flat tops, forged from 4032 forged aluminum and CNC-profiled in Lunati's state-of-the-art piston turning facility. These pistons weigh 374 grams and have a 1.130" compression height. Ring lands are 1.5mm, 1.5mm and 3mm and piston-to-wall clearance is .0025". Rings are from GM.

Connecting rods are Lunati Pro Billet Super Lights made from 4340 aircraft-quality billet steel and measure 6.125" center-to center length.

A Lunati Pro Series non-twist forged crankshaft made of 4340 aircraft quality forged steel has a 4.000" stroke and weighs 45 pounds.
