    Default Final Engine Build Plan/Schedule

    OK so we've come up with a build plan.

    Block was not align honed for use with main studs previously, which caused badly uneven bearing wear. This had nothing to do with why the valve and cam broke, but a definite problem that needs to be corrected nonetheless. Block will be getting align hone for studs as part of the machining process.

    0.060" overbore, making the motor a 468.

    Going 9.5:1 compression (like before). Stock GM crank and rods. We'll be using a race bearing this time (originally used Clevite77 bearings) upon recommendation from the machinist.

    Pistons are made by Probe Industries. Supposed to be stronger than most available and they're made in California.

    Cam will be SLIGHTLY hotter than what I had before. The last cam I had was a single pattern cam...going dual pattern this time. Here are the cam specs for the old and new cam:

    Old Cam: Isky 280H Mega
    280* seat-seat/232*@0.050"
    0.549" lift
    110 LSA
    110 intake centerline (installed at 106*)
    60* seat-seat overlap/12* 0.050" overlap

    New Cam: Comp Cams XM278H
    Intake Lift: 0.564"
    Exhaust Lift: 0.566"
    278* intake duration/292* exhaust duration @ 0.006"
    234* intake duration/244* exhaust duration @ 0.050"
    112 LSA
    110 intake centerline
    61* overlap @ 0.006"

    Both heads are getting replaced. GM OEM casting 353049 large oval port with larger valves (2.190" intake/1.880" exhaust). 1-piece Ferrea stainless valves. Hardened exhaust seats.

    Same carb and intake as before...Holley Marine 750DP and Edelbrock RPM Air Gap manifold.

    With any luck I'll end up with the same top RPM as I had before. I'm only changing the shaft seal in the pump but all the internals...impeller cut/clearances will remain the same until I know where I'm at with the new motor.

    More details to follow as the build progresses. Due to financial limitations it's lookin' like I won't be able to start reassembly until late January.

    Why don't you bump the compression up to around 10:1 ?

    What impellor are you running ? a/b ?

    Tryin' to stay pump gas friendly.

    Running an American Turbine AB impeller but once I get a different baseline with the new mill depending on what RPM I get out of that I'll probably switch over to an Agressor B.

    All I can say about that video is one end of Don Pedro to the other in 7 minutes. I like it. My personal record is 11 but who knows with the new boat.
