Pulled the 350 and sold it to get some $ back. Still shocked that it ran so well. However, I could turn the flywheel while loosening the torque converter bolts with one hand.
Trans and tcase are both good as well.
The more and more I look at it, the more certain I become about converting my 88 crew to 4x4 instead of doing a body swap. The 78 frame is trash, I don't even think I could make it into a trailer.
