    Hey guys,

    So I finally got around to measuring my cranks journals and the main caps on my 350. I don't have connecting rods...yet. The measurements were as follows:

    Main Caps:
    1st: 3.2400/3.2394
    2nd: 3.2390/3.2405
    3rd: 3.2410/3.2410
    4th: 3.2410/3.2410
    5th: 3.2390/3.2410
    (the dual measurements are for measuring vertical then horizontal)

    Crank Main Journals:
    1st: 2.778
    2nd: 2.778
    3rd: 2.779
    4th: 2.779
    5th: 2.778

    Crank Rod Journals: (dual measurements are for the forward and rear part of the journal, where a rod would be located)
    1st: 2.103 & 2.103
    2nd: 2.103 & 2.103
    3rd: 2.104 & 2.104
    4th: 2.104 & 2.103

    Not sure on the math to figure how to select a bearing size. I will be ordering new rods from TA maybe as soon as next week. I guess that will be when I can determine the correct bearing size for the rods.

    Thanks a ton,
    ~Scott
