I’ll give a good brushing when I get home from work today. This engine and transmission definitely has been swapped. They came from a d50. The guy that swapped them has no idea of year though. They were swapped out about 15 years ago and the truck has been sitting for about 13 yrs now. All he could tell me is the d50 looked identical to the mighty max.
