This Chevrolet 454 H.O. engine during initial testing produced 425 HP and 500-ft./lbs. of torque. It is the successor to the legendary LS6 454. The engine is sold completely assembled (less ignition, plugs, wires, carb and exhaust) using brand- new premium-quality parts.

NOTE: This is a Generation VI big-block engine and requires a special oil pan for Chevelle and El Camino applications. Ask one of the OPGI sales pros for an oil pan number for Chevelle applications.
