This rotating assembly offers all forged components but will create a little more squeeze in the combustion chamber (higher compression). For engines running a big turbo and/or more camshaft duration, the compression helps low RPM throttle response, turbo spool and overall power. This combination will produce approximately 9:1 compression depending on head gasket and deck height. This rotating assembly offers all forged components with a great price. It starts with a 4340 forged steel 3.400” stroke crankshaft, K1 4340 6.000” H-beam rods with 7/16 ARP 2000 cap screw bolts, and Wisceo forged piston kit with moly rings. These kits are available in .020, .030, and .040” oversizes.
