How's the surface of the crankshaft? If it's still round, a rod can be installed from the bottom side on some engines. Just disconnect the big end, roll the crank off to the side, and pull the piston down in the cylinder far enough to loosen the clamp bolt and slide the wrist pin out. I've seen guys change an entire set of babbit rods that way, or you could have the original-style rods machined for inserts after they're removed. If the crank is scored or out of round, do the full rebuild. This works on a 216- - - -the 235 has a big enough piston it's impossible to pull them down far enough to expose the wrist pin.
