On second thought, find yourself a 261, bore it out put in a bigger cam, go with duel carbs, headers, get some real HP! Then put in a modern rear end under it so you can go faster and get better milage. That would be the ideal. A hot rod six!, I hear the big GMC engine of this era still holds the land speed record for inline sixes. Might help you get across the wide expanses of Manitoba more readily! Good luck on whatever you do. J Newton
