It never ceases to amaze me how Ford built the 427 "to order", for industrial use, for specific marine use, etc., and in two bolt configuration "to save a buck er two". Why in the blazes would an irrigation pump need the 427 cubic inches, when a 390 had more meat around the bores and would probabaly have worked just as well.....why the 427? Probably has as much logic associated with it as a "business contact" or an "accounting decision".
Great info though, thanx for sharing it with us, now I know of two places that used the 2-bolt, the 1968 Cougar and the Kansas irrigation pumps! (They must have been one hell of a good lookin pump, eh?)
