I just purchased a '72 Corvette with a replacement motor. Can anyone help ID the #'s. On the right side front, under head the # is 1M1004 then under that is 5vp. On the left rear, near firewall is stamped #10066086. Someone said its a Targetmaster replacement motor. What I would like to know is the year & H.P. so I know what replacement parts to order.

Are you sure that's an 8 and not a 3? This could be it:

CASTING#: 10066036
SIZE: 350
YEAR:
MAIN CAP BOLTS: 2 or 4
NOTES: Target Master/Goodwrench crate motor, 2-piece rear seal, "Hecho en Mexico"
