Apparently in '64, the 223/262 went to a different oil pump with a 5/16" dizzy shaft (from the older 1/4" shaft) & with these you might be able to use the DS2 with fewer modifications. I also belive that Clifford has a few cams for this motor. For the most part, whatever will work for the 223 will also work for the 262. You could probably set your engine up more like some of the 300s that a few of these guys are running, if you're interested in more modern carbs, etc. I think its would be neet to have an early factory 4x4 ('59-64) with a 262 & 4spd, DS2, 2100 carb.... I think the wife would kill me if I trundled home with another vehicle though!
