Yes it will work as an assy. Crank, rod, etc. I have done it many times. In the last 30 yrs. The parts robbed up through the ’79 6hp will work. You will have to clearance the bottom of the block for the rod caps. Just a little grinding will accomplish this. Makes for a much nicer running motor and does away with one of its worse weaknesses. You still have to run 24/1 because of the wrist pin bushing and brass center main. I am looking for a way to do the 7.5 hp motor now. Comparing all size motors I can find for a solution. The 5.5hp was just easiest first.
