Scroll down about halfway down. The engine code locations are there. To properly identify your engine, you will need the 2 letter code off the front and the date code on the back of the block near the distributor hole.

YB is a 350. 500810 also confirms that it is a 350.

That is a strange one.
 I'd say it's a 1977 350, by the date code, anyway. (Oct 20, 1977) The 500810 block casting was a late 76 block casting for 350. Probably ran into 1977 also. Why it has a 75 by the distributor, I don't know. Does it have only 3 engine mount holes on side of block? Look on the front of the block, passenger side closer to the timing cover area, down low. Should be a partial VIN - looks like this probably: 27N1xxxxx Tell us what that says.

Actually, you may have mis-read the date code, probably J205?
It will still be a 350 engine though. The 77 YB would have come in a GP or LeMans. The 75 TB would have been in a Firebird, 2bbl though.

The 112517 is the Engine Unit Number (or Motor Unit Number)
The YB is the engine code (needed for my search page) The 26n522430 makes it a 1976 Pontiac Firebird. (the 522430 is the last 6 digits of the VIN of the Firebird the engine came from) That makes the date code J205, which was probably mis-read as I said. So the block was cast on Oct 20, 1975 for the 1976 Model year. Still a 350 unfortunately. With that partial VIN (26n522430) you could send it to PHS and find out what the car was originally optioned with. (for a fee though)
