Identifying sbc 350

[Jr]

Hello,
A friend brought a 73 C10 with an unknown 350. What's the easiest way to figure out what year this donor 350 came from?

Get the numbers off of the pad. Just in front of the bellhousing on the drivers side. Sometimes the last 3 digits are cast into the side of the block.

Perfect. I'll see what I can do.
