Not necessarily all that difficult, I think. Work out what your gears are, and then work backwards to find out what engines will bolt up with not much effort. (Maybe if you can identify your gears here, engine folks could trot out some candidates...)

Then you can maybe select from among choices, guided by HP/torque for each candidate, but also guided by your wallet.

Your choices may still all revolve around the 7.4 block, but even so you could possibly improve over carburetors with MPI or some such, you could improve over raw water cooling with a freshwater system, etc. Or if some newer blocks would bolt up directly, you might be able to achieve similar HP/torgue as original and at the same time reduce some engine weight and open up some space for maintenance access.
