    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 308 hp @ 5100 rpm and a solid 347 lb.-ft. of torque at 3900 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.

    why is this engine set up to run with the vacuum disconnected to the distributor,will that affect fuel mileage?

    Asked by: George q
    You would only disconnect the distributor vacuum line to set the timing on the engine. It should be hooked up otherwise.

    Could a stock th350 be used with this engine? And if the torque converter needs to be changed what is a good stall speed?

    Asked by: KrafftC10
    Yes, a stock TH350 can be used. The torque converter would only need to be changed if the engine has a different camshaft.

    I have 1981 Camaro with a 229ci V-6 mated to a Saginaw 3-speed transmission. Would this engine work with the car and transmission?

    Asked by: TC444
    With the proper mounts, this will be compatible.

    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.
