chevy id how to

I just got my Hot rod project home. Its a 55 second seris body over a contemporay frame a a 350 sb auto trans and a 12 bolt rear end, the body needs big love, so I am working from the ground uo trying to see just what I have , How can I ID the motor? is there anyway I can figure what frame this is? same with the trans Thanks Bo

For engine ID #s, I'd go to Mortec.com of Nastyz28.com.

FDacing the motor from the front to the left of the water pump on a flat spot in the block it reads " T0220dmm" and 19D484662 I can't get any thing to come up, maybe I am entering something wrong !, Thanks
