'60 and up are not Napco's unless they are the unusual 1 tons and bigger. But that Corporate 4x4 is awesome. I think you may have a 261 there. the 850 head number and the extra full flow oil hoses may be the indication. Look for the "captain's bars" above the starter. The swb 4x4's are even more rare. If that were my truck, I'd be tempted to put a rebuilt engine and trans in there (just to be up and running quickly) and clean up the interior and run that SOB just like it is. Great patina and look to that truck. More pix please.
