As part of General Motors, Chevrolet Performance is able to offer a wide and diverse range of crate engines and partial engines beyond high-performance Small-Block, Big-Block and LS engines. They are based on regular-production engines and make great swap choices for replacing a tired engine, while also enabling creative engine builders to start with an economical production engine and add their preferred power-building accessories.
Formerly GM Goodwrench, this Genuine GM Parts Replacement Engine is generally delivered fully assembled (minus the induction, ignition and starting systems) and is backed by a 36-month or 100,000-mile/160,000-km warranty when installed in a recommended application.
All new - not remanufactured! The classic GM Goodwrench 350 is offered here in the most economical Small-Block engine assembly. Designed to replace production engines used from 1973-1985, it features a durable, yet value-driven, short-block assembly and iron cylinder heads with early-style perimeter hold-downs. Better still, it includes a stronger four-bolt main block and smooth flat tappet hydraulic camshaft. This GM Replacement Crate Engine is perfect for budget conscious individuals that don't want to compromise quality!
