Scat Enterprises “Red Label Series” Rotating Assembly Designed for the GENIII Hemi Engine
The crankshaft and connecting rods are manufactured from a premium 4340 steel forging, the cranks feature a 4.050-inch stroke which can turn your Hemi into a 426 cid engine. Our crankshafts are designed after the small block Chevy journals (2.000-inch) with crank pin diameters and widths.
These specs provide a taller side wall on the crank rod journal for better oil control and reduced windage. Our counterweights have been profiled for the 6.125” 4340 Scat H-Beam connecting rods. RaceTec 2618 pistons, .180-inch wall wrist pins, and steel top rings are also supplied with our kits. You have a choice of 9.5:1 or 11.0:1 compression ratio depending on your cylinder head.
