Default 454 BBC information needed

I have 2 454 BBC engines i would like some more information on and am having difficulty finding certain things out. Any information would help. I am trying to decide which motor would be better to Use for my blower motor.


The FIRST ENGINE is out of a 1990 GMC Sierra Vin #2GTGK39N5L1502021.
Casting engine on the head: 14092360
Engine ID number: T08185CH (the engine is still in the vehicle, and it was difficult to see so I’m 99% sure this is the number)
Based on the VIN I know:
1990, GMC K3500 1 Ton P/U, 4WD 8 cylinders N 7.4L TBI, OHV 454 CID




THE SECOND ENGINE INFORMATION IS AS FOLLOWS
454 Big Block Chevy with 049 Heads on it Casting # for heads is 353049 (it originally came with the peanut heads)
Mark IV
Engine Casting #14015445
Engine ID #T1203XXZ
On the driver side rear stamp: K13, 445, Hi PERF, Pass


I’d like information on the pistons, rods, crank, cam that came with it, as well as any other details/information on the performance of the engines.

I think it's hard to get those from here , you didn't find any manuals about them ?
