Engine ID

Where is the engine stamping on a 74 318 that gives the year made, plant, etc. located at?

Look on the drivers side front of the block just below the cylinder head.

I did manage to read the numbers. GM318R 35190014. I belive it is a 71 engine. So, this could not be the original engine on a early production 74 year?

Not at the rate they were using 318's.  Hemi's were sometimes cast ahead and waited for a bit before being used but the 318 was a steady go.  And you are correct, it is a 71 engine by that number.

I also found the numbers 7181 411 stamped in front. What do they stand for? How do the numbers match on the small blocks?

For the partial VIN of the car it came out of, look on the passenger side of the engine for a raised pad. It is down low, about center (front to back), right above the oil pan rail.
