Hey all finally got some goodies for my truck but need to identify the engine and trans first!
The old guy i bought it off of changed both and wasnt sure what went in lol
The engine i'm sure is a 305 or 350 but i've scoured the block for numbers and come up with nothing, Where would be the best places to look?
The trans i believe to be a th400 but i've attached a pic of the pan for reference, is there somewhere i can get the exact model number or serial #?

Block id look behind drivers head. Usually covered in crap.

Definitely a TH400,check machined pad on front of block in front of cylinder head below alternator
