Help figuring out what this engine is?!? I got what I was a told is a small block Chevy from a friend. That's all the info he gave me and it was free so I wasn't going to turn it down. I'm trying to figure out what it came out of but I'm having a hard time. I've looked at all the casting numbers I can find and here they are:
Drivers side rear above bell housing: GM 5.7 LG SGI
Passenger side front in front of head: V0925UPK
Passenger side rear above bell housing: 14093638
Head casting number: 14102193
This all tells me a 350 from 87-88 but it could have come out of a truck or car and no way to tell. The UPK suffix isn't even on the list at nastyz28's decoder so I'm stuck. Any suggestions/answers?

14093638...350...87-95...2 or 4...Roller or flat tappet cam, one-piece rear seal
14102193...87-up...305/350
Pull it apart best bet if it is a flat tappet cam it most likely came out of a pickup, if its roller then probably a camaro or firebird.

Some quick research indicates that the heads are not particularly desirable. They are very likely a TBI application and certainly should not to be confused with a Vortec head. On the other hand, it should be easy to find a use for a roller cam block. That's a decent foundation for a useful build.

GM 5.7 LG SGI: G(eneral) M(otors) 5.7 L(iters)G(ross) S(pheroidal)G(raphite)I(ron) , a superior casting material as opposed to grey cast iron.
V0925UPK: V = Flint, MI plant, block cast and stamped on September (09) 25th (25). Couldn't find engine code "UPK" listed, but engine code "URK" would be a 350ci, 165hp, 4-bolt main engine for a Chevy C-10.
14093638: 1987-1995 car and truck 350 block with either 2 or 4 bolt mains, passenger side dipstick, and one piece main seal.
14102193: 1987-1995 305/350 engine head with 1.84" intake/1.5" exhaust valves.
