[QUOTE=techinspector1;491362]If you'll post the casting numbers off the heads (in between the valve guides), I'll run a a DynoSim of affordable parts and spit out a hp and torque figure for you, in the event you want to keep the motor and build it as a vintage 327. Also, get me the stamped alpha-numeric suffix number on the block. It's on the passenger side of the block, at the very front, on the deck where the head bolts on. If you can't see the suffix number on the block deck, that means that the block has been decked in the past and the alpha-numbers have been destroyed. On the back of the block just before the bellhousing flange, at the top of the block, is another casting number. Post that one as well please.

Techinspector1: Here's the #'s I could find. It looks like the block must have been decked at one time, can't find any #'s on the deck.

Block # just before Bellhousing = GM 3858180 also has a T-8 and J and D225 in same area.
Head # 1 = 8782461 also on head= GM1 L11 4
Head # 2= 8782461 also on head= GM2 L11 4
I'm very curious as to what I have, thanks for your time !
