...rotsa' 'ruck with that !
ALL I know is this .. these year MH's are my hobby ...and I know LOTS of people who have them ...and I know what they have. I know guys who have worked in dealerships WHEN these MH's were being sold ...and a friend of mine father WORKED at Trenton-Engine until the mid-80's when he retired.
You guys post all the links you want ... showing a 454 Chebbie motor in a 1974 Travco(when Travco was exclusively Mopar until the late 70's) ..THEN there were Chebbie power-plants because Mopar no-longer made a BB motor.
B U T .. you guys BELIEVE what you want. Have a nice day.
