I have just acquired a big block and before I get all crazy with putting it together, I thought I'd ask you guys what you thought about the numbers and stuff.

Block #'s:
GM - T12
Casting on driver rear: 14015445
casting on motor in front pass. c9b173174
casting behind timing cover : High perf ( front and back )

casting on pistons .40
crank looks to be steel forged
crank bearings are clevite - has size of .10 on it.

casting on heads;

336781

gm73

anything that you guys can tell me will greatly help
the guy who gave it to me said it may have come out of a vette.
( yeah right )
