    Hey! Can't find it in chilton's or searches.. Is there a torque spec for those 4 nuts attaching the flexplate to the torque converter on a 302/C4 combo?
    Thanks in advance!

    Converter to flexplate 23-28 ft. lbs.
    Engine to transmission is 23-33 ft. lbs.

    Edit: also says engine to trans is 40-50. I thought that other number was kinda loose

    I've never used a torque wrench on any of those bolts or nuts. Just get em tight. The transmission to engine bolts need to be at least about 50 ft/lbs as these are the same size as the head bolts, but a slghtly lower grade bolt. (head bolts are 70-80 ft/lbs) Id think the converter nuts could go to about 45 ft/lbs, being a 3/8" NF thread.

    The stock converter to flex-plate bolts are 5/16 NF and the spec is 25 foot pounds.
    The bell to engine bolts are 7/16" NC grade 5 and the recommended torque is 45 foot pounds.

    I've never seen converter nuts that were 5/16"NF. Every one I've seen on a Ford were 3/8NF
