Yep, that ones been on there before. I bought one at an estate sale year before last and haven't had time to get it running. They are sort of unique in that they use model T pistons, rods ,valves and timer. Thought I could use half a t head gasket but just enough difference in a couple of stud placement that it won't work. They also made a four cylinder model T conversion for marine use. KGB
Did they replace the cam and crankshaft so the pistons came up at the same time or does it sound like an old John Deere tractor?
Probably will sound a john deere KGB
Star Machine works in Seattle mad a complete marine conversion from a model t motor. The even used the planetary transmission for the reverse gear. My father had one many years ago and I have no idea where it disappeared to.
There are articles in the "Ford Owner Dealer" magazines of the period about these motors there are several makes
They show all the Ford parts used in them. Saved the companies lots of extra parts to make and would have made it easy to repair if needed.
