    400hp sbc

    You won't see 400hp with stock manifolds. It just won't happen. I you were Starting from scratch I would go the 383 route and keep it conservative on the cam. Vortec style heads are a good mid range power head. Summit racing uses dart vortec iron eagle heads. They come with 175cc intake runners...

    Big Block or Supercharged Small Block

    It won't live very long. You really need forged internals for forced induction. You would have to build that sbc from the crank up to handle fforced air reliably.

    283 convincor questions

    So I took some measurementsort while on the phone with the guys at checkmate. Great bunch of guys. I'm at 4.25" propshaft centerline below the keel.

    283 convincor questions

    No transom is not notched . I Ran a mirage plus 27 and it was horrible. Only thing it did was get rid of bow steer. Check my previous post about it. Bblades wants to lab my 26 bravo1. Not sure about that.

    283 convincor questions

    Well I've had the boat out almost every weekend since I bought it. Getting used to it. How it handles,working bugs out. The 26p bravo 1 just had to much stern lift with the shorty. Bow steer was down right scary at times at speed. I bought a mirage plus 27p as per local guys telling me it...

    283 convincor questions

    Thanks guys. I'm still working the bugs out of it from the po. I figured I needed a 28 or 30 pitch. Mechanic at work said to ditch the b1 and get a 3 blade but that might not be the best choice from what you guys are saying. Old Navy I didn't realize the fuel tank was that big. I thought it...

    283 convincor questions

    Hi everyone, new to the site as well as new to my checkmate. I have I 1994 convincor 283. It has a 548ci, pushing 660hp at 5500 and 694 ftlbs at 4200. It has a xr upper and a -2 imco shorty with a 26 pitch prop. Has anyone had any experience with 3 blade props? It seems I'm getting to much...

    A 283 project just getting started

    Have you tried a 3 blade prop yet? My 283 has a -2 imco on it and a bravo 1 26 pitch, and I can't get the hull out of the water. To much stern lift. I'm comparable in hp to your setup.
