[Master Restoration]

I am restoring a 1977 Peterbilt 359, frame up, the truck has a Cummins at present, I am considering switching to a 2000 year 3406 C , the engine is out of a 375 Cat Hoe, I need to know if there would be any issues , or am I heading down the wrong road, My business is Classic Aircraft Restoration and Classic cars from the 20's 30's , this will be the first Big Rig that is well under way at present, Any help or guidance
would be great, thanks for reading my question,
