Wacky 350 Block ID - Help Please
 
Yanked the 350 outta my '78 C20 for a rebuild. Don't think it is the original engine. Tried to research the stamped block numbers, but can't match them to anything. Plus, there is a double stamp on one of the numbers. Damn! Here's a pic of the stamping. Can anyone decipher this for me? Thanks in advance.

Look on the top back of the block on the passenger side directly behind the head...there should be a cast (not stamped) set of numbers..what are those ?..should be something like 397xxxxxxx or so..not sure what or where those numbers you have are

Your suffix code DRL says it's a 1979 350.
