engine number help needed.
 
What can you guys tell me about these numbers? They came from the passengers’ side of the block, in front of the head. I was told the engine was out of a 72 but who knows?
T6Z500479 and V0904TYY

TYY=1975 350 165HP 4 Bar. C-10-2500

thanks. does anybody know what the first number is?

What you need to get is the number on the block that is located behind the driver side head, but the suffix of TYY tells you exactly what the engine is.

Year = 1975
Cubic Inches = 350
Application = conv.cab
Horsepower = 165
Carburator = 4 barrel
C-10 to 2500 (meaning 1/2 to 3/4 truck engine)
