    Because I'm feeling generous.

    All in inches

    Connecting rod end play: 0.010
    Crankshaft end play: >0.012
    Camshaft end play: 0.002-0.008
    Main Cap bearing clearance: 0.001-0.002
    Rod Journal bearing clearance: 0.001-0.002
    Camshaft bearing clearance: >0.006

    Torque Specs

    Main Bearing Caps:
    Small Block with two bolt main: 75 ft/lb
    Small Block with four bolt main: 65 ft/lb

    Small Block Rod Caps
    11/32" bolts: 30-35 ft/lb
    3/8" bolts: 40-45 ft/lb

    Small Block Head Bolts
    65 ft/lb

    Small Block Intake Bolts
    30 ft/lb


    All taken from the Haynes Chevrolet Engine Overhaul Manual. It would be a pretty good idea to invest in something like this if you've never put a motor together before.
    If you don't have time to do it right, then you don't have time to do it twice.

    But if your using the Vortec heads, do not over tighten the intake bolts. It will cause damage to the intake gaskets.

    The book says 11 ft lbs on the intake for the small block Vortec, but I always do them in increments, and sequence.

    5 ft lbs, then 10 ft lbs, then 15, then final them at 20 ft lbs
    wah!

    If it ain't a Chevy, or a Peterbilt, it doesn't count!
