Title: Identifying Engine and Transmission questions
Post by: Autonutz on May 18, 2015, 11:18:14 pm
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 #?
