1978 GMC 1-ton Single Cab 4x4

I dont know for sure how much of a build this will really be since its in pretty good shape already, so lets just consider this a work log. This is a truck i just picked up last week for $1000! Previous owner stated that the motor will not run. He says he pulled thsi engine out of a running driving truck, swapped it into this truck, and now it wont run. Says it will backfire out the carb. We'll see what the problem is but a suspect a 180 out distributor.
