Hy Big Al's, I would say that that engine would be a series 2, look at the water pump and see how high the pulley is versus the 216/235 original engine. If the engine is the newer design I would suggest you check out the water pump relocation plate, that will mount the older design water pump up higher than the newer design water pump and clear the lower radiator hose and center the fan on the radiator. If this engine is the newer design, yes you will have to swap in a higher pressure oil pressure gauge, hope that helps.
