    Here are a few shots of the final assembly of the new motor.

    The crank, whittled from Ken's old door stop.

    Neat thing about using small block Chevy sized journals is factory coated rod shells in any taper desired.
    P1020624.JPG
    Big journals -big radius = less flex
    P1020625.JPG
    Stretching the rod bolts
    P1020626.JPG
    Pistons whittled from forged bar stock, hard anodized with low friction coating
    P1020629.JPG
    SBR billet cases and extra heavy duty cam chain
    P1020630.JPG
    Oversized PTO shaft to go with the oversized main bearings, custom sprocket to fit
    P1020631.JPG
    92mm stroke, 80mm bore, 9.3 compression, 924.8 cc
    P1020633.JPG
    Hydraulic tensioner, oversized, tight clearance oil pump [from old engine]
    P1020634.JPG
    Cylinders coated with Total Seal Quick Seat [dry film lubricant]
    P1020635.JPG

    The Fullauto head with 3mm over valves will be transferred from the old motor.

    No, it's one of my prototype non-symetrical cams.
    It runs on roller bearings on both sides plus a ball bearing behind the sprocket to control end float.

    As bulletproof as it gets. I think I want to live in Colorado where they have 40 hour work days. I'm in awe of how you manage to accomplish so much.

    Will that require a TTI behind it or will you go with standard gearbox and careful throttle hand?

    There is a wide ratio TTI setting there also.

    And then if things go real well there is a little Garrett setting there too.... Maybe someday.

    Nice Jim,
    hope you put many miles on this setup. Love the eye candy. Lots of dollars in there.
    Cheers,

    Jim,

    Please excuse my ignorance, but what's a "Garrett"? Some sort of aerospace derived gearbox?
