I have a 223 in my 65 Divco. All casting #'s, except the timing cover, are C3###. The timing cover is C4##. Doesn't mean its a 63, just that thats the last year they made a change to the casting. But, this truck should have come with a 262, according to Divco manuals. Anyway, I also believe in the 7 P's, so after reading the posts on Dizzy conversions, I got a 64 oilpump, a Duromax (300)dizzy with the 5/16 hex drive,extra 223 dizzy gear, even extra snap rings and an extra oilpump hex drive.
Went to change them out, the old gear was pinned in place, as was the 300. Drove out the pins, and removed the 2 gears, put a vernier on each shaft, to see how much I would need to ream the old gear to fit the 300 dizzy shaft,...they were the same diameter! Measured the hex oilpump drive shafts, and they were both 5/16! (Although the 223 was about 1/2" shorter)All I had to do was heat up the "old" gear, and slide it on and put in the pin. Conversion done!
My theory is this; The truck did originally have a 65 262. When they replaced it, the 223 wasn't complete. i.e. missing an oilpump or a distributor, or both. So, they got a dist. gear for a 223, reamed it to fit, and used the dizzy and oilpump off the 262. BTW they also used the intake, cause it has a carb heater under the carb. To eliminate it they would have had to replace the studs the carb mounts on with shorter ones, so they just used the heater as a spacer, and didn't plumb it up.
Ah,.. the fun of working on 50 year old vehicles, and trying to figure out what some P.O. did! Jim
