General Motors Introduces New 350 Cubic-Inch V8 Service Engine

Giving new life to old GM trucks.


  • GM is offering a new 350 cubic-inch V8 engine for older GM trucks.

  • Backed by a transferable 3-year or 100,000-mile warranty.

  • These new engines are designed, engineered and built in the United States.


There’s a new original-equipment, 350 cubic-inch V8 engine available from General Motors, or more specifically, its GM Genuine Parts division. This new 5.7L V8 seeks to be an alluring choice as a replacement engine in the company’s various models.

Three variants of the 350 cubic-inch V8 engine are available for older Chevrolet and GMC vehicles. Gen 1 covers trucks, vans and SUVs from 1987 to 1995, Gen 1e LD is offered for light-duty trucks from 1996 to 2002, while Gen 1e HD is suitable for heavy-duty trucks from 1996 to 2002. All three are backed by a transferable 3-year or 100,000-mile limited warranty.

These engines are designed, engineered, tested and built in the United States, and feature brand-new four-bolt main blocks that can be fitted with roller camshafts and a mechanical fuel pump. The cylinder head and block castings are new, not remanufactured, as are new valve covers, the oil pan and the timing cover. The V8 also gets forged steel crankshafts and dipstick tube provisions on both sides. The heads, castings and other components are made from CNC machining.

“Building on the history and versatility of the original 350 first available in Chevrolet models such as the Camaro and Corvette, this engine continues to deliver,” stated Andrew McKittrick, manager of GM’s propulsion portfolio, in a press release. “Every GM Genuine Parts engine incorporates our very latest engineering technology and product enhancements to offer a reliable and dependable product for our customers.”

According to General Motors, 268,029 350 cubic-inch V8 service engines have been sold since 2005, and 4,000 dealerships are authorized to sell the replacement engine. In addition, there are 19 crate performance engines currently available at Chevrolet that use a 350 block.

GM also offers a wide range of engines through Chevrolet Performance. Back in June, it released the all-new LS427/570 crate engine, a 7.0L  V8 based on the LS7 production lump with an estimated output of 570 horsepower and 540 pound-feet of torque. A wide selection of small-block, big-block, circle track, LS and LT engines are available as well.
