I was looking at a small block today w/ casting #3956618, casting date C 139.
It has been decked so no numbers on the pad.It has the 3941178 302 crank, I could tell by the crankshaft flange.The heads and intake are later pieces.
I found the VIN on the rough casting near the oil filter flange, but it was very hard to read.
The best I could tell was -
Couldn't read the 3rd to last number but for sure starts w/ 627.
Is that enough info to see if the car might be in the data base?
What else should I look at to try and confirm it's a DZ ?
