Here's what I do know...it's a 350. From below at the rear of the engine on the driver side are the numbers 350 and the #6 below 350. On the left bank cylinder head (driver side) is what I believe is the engine serial number 8H373205 (see image) Can anyone decipher those numbers for me. The only I think I understand is the H means it was built in the Flint plant. Do any of those numbers tell me the year? P.S. sorry the image is upside down.
