Find someone who knows how to aim the spray nozzles in the oil pan when the engine is reassembled. That's critical to the connecting rods staying put because the troughs in the oil pan only lube the rods at idle. Aluminum pistons for a 235 will work with a .060" overbore, and you'll get better acceleration and less rod bearing wear than with the original cast iron pistons. It's also possible to machine the rods out for removable bearings instead of running the Babbit-lined rods. Those bearings are getting scarce, but a rod bearing for a 3 cylinder Perkins Diesel engine will work if you regrind the crankshaft to the right diameter. Good luck!
