[baggedjeep]

i have the opportunity to obtain a 1982 4.2L Inline 6 that runs great, but i know nothing about them..... I only have a couple of days to tell him i want it (for free) and want to become technically saavy....
my questions:

1. its an AMC motor, right? or is it some derivitive of like ford or chevy?
2.factory horsepower?
3.what tranny does it use? can i use a ford tranny or a chevy tranny?
4. anything else that would be informative and useful?

thanks a lot
