    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.

    I am looking at replacing the 305 TPI in my 86 IROC Z28 to a new 350, would this engine work or is there a different 350 that would work with keeping the TPI?

    Asked by: Billy113
    This engine is not very fuel-injection friendly due to the cam specs. Also your engine has a 1-piece rear main seal so you would need a different flexplate/flywheel and balancer. Any upgrade to a 350 will require some modifications to your TPI, as it is specifically calibrated for use on the 305. It can be done, with a custom chip burned for the combination, possibly some porting at the base of the manifold, different knock sensor, etc but it's definitely not a plug and play installation. The closest engine to this for you would be p/n 059-HP57.

    I have a 1927 Roadster which is running a 1987 GM 305 with a weiand 142 blower with a Holley 750 supercharger carb. Would this be the 350 to use ? Will the intake manifold and 350 transmission bolt up ? Will the cam work with the blower.

    Asked by: Bubbamace
    You will need to know if this is a 1 piece rear main seal engine or 2 pc rear main seal. This is a 2 piece rear main seal engine. The cam may need to be changed depending on how much boost your are using.

    Will a 1975 TH350 with a stock torque convertor work with this engine. GM indicate a high stall speed may be required. Why?

    Asked by: 37barry
    GM suggests that because the cam profile moves the optimal RPM range up. The stock converter may work but the vehicle will run better with a 2000 stall.

    Hello I am looking to get a 809-19355658 350 290 crate motor and want to know if an edelbrock 2102 cam will go with it and about the hp after installation. more or less horse power with the 2102 cam. Also a 3 duce set up for the carbs. thanks Doug

    Asked by: Solipon
    An Edelbrock 2102 will go into this engine, however it is smaller than the cam already installed. You can install a 3 duece setup on this.
