The problem you will have with all of the spark ignition and diesel engine you have listed is they have blocks which are approximately 1.25 to 1.50 inches longer than the 148. The engines will bolt up to the bell-housing, but the tin and possibly some linkages will have to be modified or replaced from a donor tractor (factory diesel 430 CK).
The only realistic higher horsepower alternative is a 159 CI spark ignition engine which would give you about 7-8 additional hp. The 159 has the same dimensions as the 148 ci engine and is a true direct bolt up. This is the 530's standard spark ignition engine, and as such should be far more plentiful from an acquisition and parts availability perspective.
These engine swaps always get more involve and expensive than expected. Does the 430 have enough cooling capacity for a larger HP engine? It may not be a problem, but wouldn't it be grand to make the swap, only to find out you need to locate a 530 radiator? Have you considered trading for a 530CK or one of the "newer" 580s?
