I just recently got an 82 ford mustang 2.3L carburated automatic. i got it for 400 bucks and the car is in great shape only 76k orig miles. well someone never changed the oil i think and it has a rod knock, actually has a hole in the oil pan now. well anyways i got my hands on a good long block out of an 89 ford ranger. and i was wondering if i could use this block in my car. i was gonna reuse the head of my orig engine and put it on the 89 ranger block. any information would be great, i been trying to look around and i couldnt find exactly what im looking for. also if this block didnt work out could i get a fuel inj. used engine and put it in my mustang, useing my carbuator? i am having a really hard time finding a used engine that is carburated. is the head different on the two? any block differences. thanks --David
