What would you do?

I have a nice 66 327, 4 on the floor long bed that I bent a rod on. So it is parked but the truck is totaly straight, all chrome is in great shape and original plus the numbers match.

I also have my 68 (my all-time favorite body style and much more comfortable for daily driving) that has a 350 that was installed later by the fire department that previously owned it. I am driving it now but I have no idea how long the 350 will go, runs good but still do not know if there are many miles left on her. Anyway, I promised myself to not swap parts from one to the other but I would love to rebuild the 327 and put it in my 68. Then I would have my favorite body style AND my favorite engine combo. BUT, the 66 numbers would no longer match and it is in great shape, I am the third owner, my Dad being the 2nd who is indifferent to what I want to do.

Both are long beds so I am inclined to just build my ultimate truck but what would you do?
