    The Chevrolet Performance 350ci HO Base Engine doesn't sacrifice power or durability with its four-bolt main block, nodular iron crankshaft, Powdered Metal steel connecting rods and cast aluminum pistons. Chevrolet engineers add to this strong foundation a pair of cast iron Vortec 64cc cylinder heads with 1.94'' intake and 1.50'' exhaust valves, yielding a healthy but streetable 9.0:1 compression ratio. The camshaft is a modern dual pattern interpretation of the 1965-67 Corvette 327 camshaft with more exhaust lift and duration for improved combustion chamber clearance and less intake lift/duration for more cylinder pressure!

    GM Warranty

    19210007 is rated 4.0 out of 5 by 2.
    Rated 5 out of 5 by from Incredible 350 w/ lots of power! Bought this a few months back and am just now wrapping up the install. Motor fit like a glove in my '77 C10 and provides a ton of power for a 350 crate motor, would recommend this over the other 350 crate motors GM offers. Only catch here is that given the extra HP this 350 puts out I had to buy a new manifold, distributor, alternator and fan to power the motor and keep it cool in the Texas heat. I thought this might be an issue going into the project so I was not "surprised," but something to consider. All in all, can't beat the power and warranty offered on this motor!

    Rated 3 out of 5 by from Runs Great Bought this motor back in September finally got it in, had a few issues with it. Could not get one of the spark plug to thread in so had to buy a thread chaser. The major issue we had was when running the engine at higher rpms the engine had oil coming out at the rear of the oil pan, we pulled the pan and found that the pan gasket had been rolled over during installation at the factory. Now that we have everything fixed right the motor runs great

    Asked by: will121121
    This is a 1 piece rear main seal engine so you will need to purchase a new intake manifold.

    Will this swap and fit my 97’ Silverado 5.7 vortec wilth no modifications? 

    Asked by: DG23
    This engine will fit your Silverado. You will need to retune the EFI system and connect the transmission with the proper flexplate.

    What is best engine for my 1985 chevy k5 blazer 4x4 with 35 in tires,automatic 700r and i will be towing a 18ft travel trailer weighing 3,500 lbs 4 times a year

    Asked by: Cesar7
    This is an excellent choice for that application. It has a mild camshaft profile and Vortec heads so it makes great usable power for everyday use. Please call and speak to one of our techs about the other parts needed to complete the installation of this engine in your vehicle.
