It would be a tight fit but when you factor in the engine weight, roughly 2200 pounds, you'll need to seriously beef up the front end to carry that weight.  I'm not even sure a half ton pickup would be able to handle it.

If you're seriously considering a swap, I would suggest a Cummins 4BT for this because you'll get a good mix of fuel economy and pulling power.

Just remember that displacement has little to do with engine dimensions when you're comparing a big block V-8 to an I-6. You will probably at least have to extend the firewall into the cabin a tad to make it fit.

Good luck with the swap and keep us posted with your progress!

Well, it would definitely be a tight fit. I think you should look for another cummins for better performance.
