Hi i just bought a 454 bbc motor for $275 it runs pretty good for a motor that the owner told me was very tied and needed to be rebuilt badly. What i need help on is thatvi was looking up the numbers on the block and stuff to get as much info as possible and ran into a problem. I will do my best to not confuse anyone.
So the block # is 14015445 to the right of that it says P gm 714 and then D 1004

The back of the block where flywheel goes it says H PEP F8

The intake says 10052952 BzD or maybe BzC and has 5.5.88 l7

The heads say 14081045 (would like to know if any good)

Here is where im completely lost and need help. There is nothing on the deck area in front of the head were most motors are stamped absolutely nothing however just above the timing cover it says T0502TBD what is this motor? In terms of HP/Torque and is it a stock or create motor? Any info would be awsome as i would like to know what im getting into for a rebuild and power wise.

 

This must be a hard one to figure out? Its probably going to be a phantom motor lol the one that exists but no one ever see's or can find.
