My OD is a Warn, and as the transfer case is a dana 18 there isn't any advantage to the BW as the transfer case is always turning in any event, and the BW adds length. Pretty much all of the early jeep OD's are the Warn or similar. My tires are 6.00x 16's although they may grow to 7.00 x 16s if the engine mods give me the grunt to turn them. I have no desire for big wheel and tires on the old jeep.
181 mercruiser engines are plentiful. The problem is that no one made non-marine manifolds for them as the are 8 port heads, rather than the 6 port heads of the 2.5 mercs and 153 Chevys. I'm going to try my hand at building headers for the 153. If that goes well I might play around with a 181 at some point down the line. Of course I'd need another jeep to put it in
