  • I'm planning to install this engine in a 1981 Corvette. Will everything match from the stock 360 engine? For example, intake manifold, exhaust manifolds, all bracket holes for alternator, AC, etc? If not, what engine would be recommended? Thanks!

    Asked by: 81Vette
    This engine would not be a direct replacement for your stock engine, it will work in your Corvette but some modification and manipulation may be required.

    Does this engine have provision for a mechanical fuel pump, or does it need an electric? Also, does it come with a dyno sheet? Thanks.

    Asked by: mep2jr
    Yes this engine will accept a mechanical fuel pump and we do dyno every engine before it leaves our facility.

    I have a 1987 Chevrolet Silverado 350 with factory Fuel injection ,what would be needed to make this application work ? I have true dual exhaust with dual hi flow cats and like to retain factory EFI ? Cam sensor ? Will it work 

    Asked by: MarkO1987
    For your vehicle I would recommend either my part number BP38302CT or BP38301CT, both of those engines are designed to work with your factory fuel injection. This 350 part number that you are currently looking at was designed to be ran with a carburetor.

    Wat will I need to put this engine in my 1999 k2500 pick up 

    Asked by: Henry 99
    Henery, we would not recommend this engine in a 1999 K2500 with factory fuel injection. The cam that we have installed is designed and recommended for a carburation application only.

    This Blueprint setup is exactly the re-build I am looking for in my Marine engine. 350 SBC engine (Mercruiser). Would this work? Or do you have a specific marine rebuild with the vortec heads, roller cams with 5" lift set up? GM Casting number 14098242

    Asked by: SRC3
    If this engine is used in a marine application unfortunately it will not carry a warranty. We do offer our engine part number MBP3550CT or BP3830CT that are both 350 Chevy based but would be more of a performance build and not a stock build.

    Does the engine use L31 heads? I want to use Jegs intake #555-513004 with this.

    Asked by: c10builder
    The cylinder heads that we are currently using on this engine build is a factory Chevy 906 casting. The intake that you are looking at would work on this engine setup.
