It's definitely on a track/kick frame so im guessing 1.6l 8v 5spd w/ sami case on yotas? Looks like a swb too, maybe 100"
edit: just looked closer and its got an automagic!
I have a 4.3l vortec motor that's mated to a th350. Ran fine when pulled from a friends project. I have everything you would need for a swap except a transfer case or transfer case adapter.
Here's a list of everything included with the combo-
B&M shifter w/ cable
Jims performance ECM
Wiring...
