The best value crate engine in the GM Performance Parts lineup!
The 350/290 HP is the most popular GM Performance Parts crate engine because no one can deliver such performance for this kind of value. 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 it's affordable, don't think that it's 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, it's 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.
We've also loaded the 350/290 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. Add an intake manifold, carburetor, ignition system, starter, balancer, and water pump, and you'll be ready to hit the road with a fresh new motor. All of these parts are available from GM Performance Parts, and with its low price, you'll have no problem finishing off the 350/290 in style and affordably.

350/290 HP DELUXE

The 350/290 HP Deluxe combines GMPP's most popular crate engine with an aluminum intake manifold and chrome dress-up kit to create one of the most stylish and value-driven engines on the market. The chrome dress-up parts include the valve covers (with push-in breathers and "T-bar"-style hold-downs), timing cover and air cleaner. Like all GMPP crate engines, the 350/290 HP Deluxe starts with a brand-new block. And it's a strong one, with four-bolt mains. It also includes a smooth hydraulic camshaft and durable aluminum pistons.

It's easy to understand why this economical crate engine is so popular. It features four-bolt mains for strength and it's filled with premium parts, including a smooth hydraulic camshaft and durable aluminum pistons that deliver an 8.5:1 compression ratio?making it a great, time-saving alternative to rebuilding a tired, two-bolt-main core engine.

GMPP also has all the parts you need to get your 350/290 HP engine running in your project vehicle, from the starter and distributor to the plug wires and more. And if you want even more power, our high-performance cylinder heads will take this stout small-block to the next level.
