paulrhd29nz Posted November 23, 2020 Share Posted November 23, 2020 The two piece head is interesting. So is the sump. Do you have the top of the head ? Link to comment Share on other sites More sharing options...
dustycrusty Posted November 23, 2020 Share Posted November 23, 2020 That is a 1940's- early 1950's Ford industrial or '40-41 light truck or GPW engine block (due to the fuel pump block-off plate) based on the Ford "N" series Tractor engine with a few somewhat crude modifications (the trimmed off bellhousing where the starter mounts and the welded in water port where a core plug once resided). No idea about who made the (marine??) conversion parts. 1 Link to comment Share on other sites More sharing options...

pcolleary Posted November 24, 2020 Author Share Posted November 24, 2020 thanks . I can't find a picture of anything close. I only bought it because I have never seen one like it Link to comment Share on other sites More sharing options...
dustycrusty Posted November 24, 2020 Share Posted November 24, 2020 heres a stock ford "N" block. notice how the I & E ports, water pump and tappet galleys line up. Your cam gear is also a give away- not only its design but the SLIGHTLY off-set slot on the end of the camshaft drives the ignition system on a stock pre-1950 Ford tractor or industrial engine. 1 Link to comment Share on other sites More sharing options...
pcolleary Posted November 24, 2020 Author Share Posted November 24, 2020 That definitely looks like it is the block Link to comment Share on other sites More sharing options...
pcolleary Posted November 24, 2020 Author Share Posted November 24, 2020 Hi Here are the timing cover , mag and water pump 1 Link to comment Share on other sites More sharing options...
dustycrusty Posted November 25, 2020 Share Posted November 25, 2020 Still based on a Ford, just much weirder now.... A stock Ford camshaft-driven distributor would bolt right up to that empty hole with the 2 threaded holes in that front cover. It looks like the water pump was driven off of the backside of this cover, behind that round cover with the 3 hex and 3 allen head bolts, and the Fairbanks Morse Magneto was driven in line behind the pump off of the shaft at the rear of the pump with that rubber "gear" serving as a lovejoy type link between the two? Thats a whole lotta re-engineering and low volume manufacturing for a nominal 20 h.p.! Link to comment Share on other sites More sharing options...
pcolleary Posted November 26, 2020 Author Share Posted November 26, 2020 I agree Link to comment Share on other sites More sharing options...
Layden B Posted November 27, 2020 Share Posted November 27, 2020 That connection is called a Simms type magneto coupling. It has one more cog on one side than the other making small incremental adjustments in shaft timing very easy. Of course also allows for some shaft mis-alignment and easy assembly/ disassembly.
