putting in a smaller motor, than a 460
i have a 1987 24 foot ford motor home with a old 460 in it with a three speed tranny, its killing me at the pumps, is there any way to either swap out the tranny for a 4 speed or something with o/drive, etc etc or is there a better motor to swap in with a good tranny etc? like a new yet wrecked truck combo etc? i never put my foot down on old 460, but it raceing over 3000 rpm on highways, yike---////////////////////$$$$
