junk yard engine ID...

I have my eye on a 400 sbc engine (3951511 left rear casting no.) with 76 cc heads (3998997 casting no.s)

I'm wondering if the stampings on the deck pad in front of the right head will tell me if it is a 4 bolt main for sure, and more importantly what pistons or what compression ratio it is.

these numbers are..

12S216538 TO217CKP

Thanks for any help on this...I can't pull the heads unless I buy it first.

the 4 bolt were made 70-72 then they switched to 2 bolt.
for some reason I think the two bolt is more desirerable then the 4 but I can't remember why.

That's a 1972 400/170hp, 2-barrel automatic out of a Caprice built at St. Louis; should be a 4-bolt block - almost all the 511's were.
