This specific kit (EAG13202040) provides a 5.8L/357 cubic inch displacement with a 4.040 in. bore and a 3.480 in. stroke, suitable for Small Block Chevy engines. The kit includes a cast steel crankshaft, hypereutectic aluminum pistons with a flat top and two valve reliefs (+7.00cc), and forged 5140 steel I-beam connecting rods measuring 5.700 in. center-to-center. It also comes with pistons, piston rings (Plasmamoly facing), rod bearings, and main bearings, all at stock undersize.
