Drop some performance into your Street Rod, Muscle Car or Truck with these genuine GM Performance engines! All GM Performance engines include a 24 Month 50,000 mile warranty. GM Performance Parts believes that everyone should be able to afford a high quality GM V-8 without going broke. The 350/290 is an answer to those car crafters who demand maximum return on their money. But, just because its affordable, dont think that its a stone. The 350/290 delivers 290 hp @ 5100 rpm and a solid 326 lb.-ft. of torque at 3750 rpm. With those kinds of numbers, its the perfect replacement engine for the millions of GM vehicles that shipped with a small-block. Got a tired, old Chevy that needs a lift? This is the crate engine for you. It is loaded with a four-bolt main bearing block, aluminum pistons, and a hydraulic camshaft. The cast iron cylinder heads are designed to be extremely durable while still providing good airflow through the engine. The 350/290 will ship to you as a Base-level long block.
