19355658 Replaces 12499529 Chevrolet Performance 350 Crate Engine 290 HP HO 

Our lowest priced crate engine.

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, high performance
GM V-8 without going broke.

The 350/290 is an answer to those car crafters who demand maximum return on their
money. However, 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 project car 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.

The oil dipstick for the 350/290 HP engine for the right-hand (passenger) side of the block is 10190942 (indicator) and 12552920 (tube). If not using right-hand dipstick, use plug 09421743.
