Can I put a 96 5.2 block in my 68 Fish?

So, this thread may sit for a while. I hope I find someone that can/wants to contribute. I will update in the late spring. I bought a 92 Dakota LE with a 5.2 and 140K. It seems to be solid, though I may have to replace the Idle Air Control Motor (IAC) (some weirdness with the Idle at times) Any way, I will drive it during the winter here and do my research. I will do the transplant in the late spring. I will also do a forward or talk to a moderator to have this thread moved to a more suited place. Thanks for all your views. Add info if you have it.
Cheers
