    What are the specs on the 6 bolts from the pressure plate to flywheel and the bolts from bellousing to engine? Thanks.

    My book doesnt give any specs, just says to tighten them. For the pressure plate, it says tighten in a cross cross pattern until the spring pressure is taken up. Just give the bolt a little "uh huh" with the ratchet and you will be fine. /forums/images/graemlins/thumb.gif

    I just tighten them til the lock washers are flat and they're nice and tight. Has worked great on the last three motors.

    If the bolts are 5/16" tighten them to 15 FT/LBS.
    If the bolts are 3/8" tighten them to 25 FT/LBS.
    Make sure you are using pressure plate bolts and not just a regular bolt, pressure plate bolts have a special shoulder on them that locate in the bolt hole.

    My Chilton's manual said something like 40 ft/lbs IIRC.
