Oil dipstick location helps with later blocks as does 1-pc rear seal if you can see that if it's on the ground with no flywheel. Honestly the stamp pad is the best way to tell what it is without too much work-assuming it's never been built and decked.

True about the age of the post, but be honest with yourself -- you have not the slightest idea what he meant, only what he said. What I stated here was also correct ten years ago and is still correct today. None of that alleviates the fact that the post was incorrect. This is a prime example of how false and untrue information gets spread over the internet.
I started building race engines around 1962.. The favorite sbc for some of the racers in those days was a Chevy 301 cu. in.. Do you have any idea how many ways that engine can be built using ONLY factory Chevy parts?.. (1) bore a 283 block to 4 inches.. (2) put a 283 crank in an early 327 block. (3) use a factory built 302 engine. (4) put that same 302 crank in a 350 block, just to name a few, but there are more.. And to top it off, none of the "factory stamped numbers" mean a damn thing in each of those examples.. Those numbers only tell what the block started out as.
Just for the record, I didn't revive this thread, someone else did that......
