I have a 3932386 block dated I68, with a pad stamp of V0910XK. I believe this is a is a 69 block 350 4 bolt and I think it's a truck block. Can anyone verify my findings? Also on my Munci tranny there's a metal tag attached to the lower left bolt of the cover, and with out removing the bolt to see all the numbers, the numbers 915085 are stamped on it, any ideas?
