360 year identification help

I looked and am not coming up with anything. I take it the the driver side of the block doesn't have any numbers cast into it? What about the vin pad by the pan rail on the driver side? If the motor has never been rebuilt the bearings almost always have a date stamped into them on the underside.

The only numbers cast onto the drivers side is the block casting number followed by 360. I didn't even think about the vin pad by the pan rail. I just went out and dug the grease off of it and the vin isn't very readable cause they let the die slip when they punched it but I didn't need the vin anyway, BUT a big 74 followed the vin number and was very legible so it is probably a 74 since it was made in nov. of 73.

Thanks alot SD. I think you helped me solve it.
