I wonder if one of those 16 HP sideshafts would swap out with a Kohler 16 HP Cast Iron sideshaft? My friend has one of those HEAVY old FORD LGT's where he took the engine to have it bored. Well...some hillbilly, backwater, mechanic/machinist impersonator bored it OFF CENTER and reassembled it only to have it throw a rod! It's laying in a heap in his garage now. Warning: DO NOT go to the cheapest, no-guarantee fly-by-night shop claiming to do the job. You may lose an engine! That engine was so heavy it took both of us and boards to lift it into the trunk of his car. If you're ever trying to load a heavy piece like that...what I did was take two 6 foot long 2X4's and put them side by side on the trunk and slide the engine up the boards. When it gets to the tipping point, let it STAY on the boards, and merely raise it up like picking up a wheelbarrow and the engine will be MUCH EASIER to raise when you go to unload it. Just push down on the ends and leverage will raise it up for you, just have someone there to keep the engine balanced and from sliding down the ramp like a kid at the waterpark and land on you!
