This new SBC 350 delivers 290 hp @ 5100 rpm and a solid 326 lb. -ft. of torque at 3750 rpm. This package includes all the same parts and features as our other Pace Pac 290HP packages but we've changed out the intake with a retro looking Edelbrock Performer EPS that we have also drilled and baffled for a rear PCV valve. The valve covers are a reproduction finned aluminum with the Corvette script. To keep this look going we eliminated the HEI distributor and put in a small cap unit and an external remote mount coil. This package is shipped as shown.

The 350/290 HP is the most popular Chevrolet Performance Parts crate engine because no one can deliver such performance for this kind of value. Chevrolet 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.
