    The Chevrolet Performance 350/290 Base 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 Base 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 300 hp @ 5100 rpm and a solid 335 lb.-ft. of torque at 4200 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!

    Rated 5 out of 5 by from Great replacement engine This engine is a great replacement. It has sufficient power all through the rpm range for a street motor. I have received several compliments on the exhaust note the motor produces through flowmaster mufflers

    Rated 4 out of 5 by from Almost a drop-in Installing in an older Corvette. It came with bronze pilot bearing installed and oil dip stick plugs for left and right side in a bag in the valley. Keeping the old stock unvented Vette valve covers was a problem. This block does not have the rear valley vent casting. It was also necessary to drill and tap the 1/4 - 20 hole for the spark plug heat shield in the right rear of the block the other three were correctly drilled and tapped. Shipping was fast only four days.
