    Default SBC in a jet boat???

    I'm sitting on a couple of SBC stroker motors, roughly 400hp don't know torque, they were built for a twin engine offshore boat. I've since sold the boat and don't have a use for these yet.
    Anyhow, my buddy has the idea that he wants to slap a blower on one and shove it in a jet. To me it seems like its just too much work for the SBC. Am I way off? I see the LS builds that a few guys are doing, but seems like that's a different subject.
    Is a blown SBC in a jet a waste?? or kind of a fun, lets do something different deal??
    I know moving boats is about torque over HP
    Just seems like the SBC would screaming all the time to develop any speeds....
    Thanks

    Blown SBC would be a blast-
    Way more HP than a stock olds @ 320 HP or so
    My stock 350 Suburban motor turns an "A" impeller to 45-4600 r's, ~325-330 hp
    'low end torque' is for pulling a gear- like a mercruiser or vdrive, etc.
    Do it
