Retail $2,395 Our Special Price $1,995 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.
