    with just a bototm end minus balancer and oil pan, how could i tell which of the following two are what the bottom end is, i picked one up a little while ago with this tamping code:

    1974 CMR 350 tur hydro trans. - 145 2 A
    1978 CMR 350 m/t L82 4 220 4 Vette/Z-28

    i looked up 78 vette info and found out that sequential unit numbers were 400,001-446,558 so if vin code on block is between them, then hmm.. http://100megsfree4.com/corvette/1970/vet78.htm


    thanks

    Check the back of the crank for a pilot bushing. It would be the vette engine IF it has the bushing in it.... I'm not sure but I think both might be machined for one...

    The L-82 had forged pistons, crank plus 4 bolt mains. I would assume that the other would have had cast pistons and crank.

    Let me know the vin my 78 L-82 no longer has the original engine.... Maybe its mine /forums/images/graemlins/thinking.gif No thanks I don't want it back
