The length will get you. I had an M37 with the 3-53 and it was tight. The 4-53 is approximately 8 inches longer which would put it 6 inches into the radiator. I really liked the 3-53 in my truck, but I wouldn't too excited about this engine for a power wagon transplant. Parts are incredibly expensive. I spent ~$900 on parts for mine and there was nothing really wrong with it when I started (some oil leaks and stuff), and I was getting dealer pricing on parts. It sounds like the truck is worth $50, though.
Enjoy,
