I'm pretty sure the Abracadabra runs around 102+mph @ 6200+/- rpm according to it's owner . Your buddies boat should be running 112+/-....not 100+.
    Is his boat called...Got Issues (jk wink ).

    I think a lot of guys that posted here may not have realized that the stock stroke is 4.00 and a 4.25 stroke (.250 longer than stock) gives him an extra 28 cubes. wink You know Hal, I was starting to think the same thing!
    So, for those of you who need a little math lesson.... Here you go!
    (Bore x Bore x Stroke x .7854 x # of Cylinders) will give the cubes of a said engine.
    So a 454, 60 over, with a 4.25" stroke will give you a 496.
    4.310 x 4.310 x 4.250 x .7854 x 8 = 496 cubic inches

    Taylorman,
    I would say that 780 would be attainable with 632 freakin cubic inches. you can't beat cubes for hp. But we were talking about an engine that had less than 500 cubes making 730+ hp. that is 1.47 hp per cubic inch. the 632 is only making 1.23 hp per cubic inch a much more believable number on pump gas. But what do I know. Us dumbass rednecks just don't know how to build em like them boys in Cali.

    Omega It's not you or anyone else is a dumbass redneck, but just because you can't build a 496ci 732hp motor in your garage doesn't mean it isn't possible. All I see is a lot of people saying they can't see it being done because none of the well known "Engine Package Builders" haven't done it. What I don't see is anyone actually saying WHY it can't be done.
    Chet said he can't see a 700hp motor using cast iron 990 heads with a lot of port work, but has yet to explain why that's not possible. I see a lot of people having a hard time believing what my motor makes, but no one with any real reasons why, just specs from other motors that Big Names sell.
