Chevrolet Performance’s 454 HO crate engine is a Big-Block bargain – an affordable engine with performance specs that will make you think it’s 1970 all over again, including 438 horsepower and 500 asphalt-wrinkling lb.-ft. of torque. A latest-generation block casting with four-bolt main caps is the Big-Block engine’s foundation and features an all-forged rotating assembly for great strength and durability. It also uses a smooth hydraulic roller camshaft for excellent drivability and a broad performance range. Rectangular-port cylinder heads with large, 2.19/1.88-inch valves, round out the assembly. The engine package includes a water pump, balancer, 14-inch flexplate and an aluminum intake manifold. Simply add a carburetor, ignition system and starter and the engine will be ready to roar. All of the necessary parts are available from Chevrolet Performance.
