SBC 383 Balanced Rotating Assembly, Eagle B13005E030

Eagle B13005E030 is a balanced Street & Strip rotating assembly for a two-piece-rear-seal small-block Chevy build. Its 4.030-inch bore and 3.750-inch stroke combination produces nominal 383 cubic inches.

The assembly includes a cast crankshaft, 5.700-inch 5140 steel I-beam rods with 3/8-inch ARP 8740 bolts, hypereutectic KB flat-top pistons, piston rings, King SI rod/main bearings, a damper and a flexplate.

Eagle lists a .927-inch piston pin and 1.433-inch pin height. This package is intended for naturally aspirated, pump-gas street-engine builds. Confirm block machining, clearances, ring gaps, rear-seal arrangement and the full engine combination with the engine builder.

This is the rotating assembly and listed accessories, not a complete engine. Eagle specifies that its products are not for pollution-controlled vehicles.
