Old ford trucks?
Unfortunately, Ford did not make it as easy as Chevrolet did in retro-fitting new engines to old cars and trucks, they change quite a bit over the years, and makes it harder to do a swap like you want to. That said, though, it may still be possible. But you will most likely need some VERY experienced advice and help to get it done right, as 17 years is a rather big time difference in engine generations. I can't help you, I'm a Chevy / AMC guy, but I DO know that Fords tend to be tougher to customize this way than Chevies, but go for it. You got the motor.
