Does anyone know what the stock hp and torque is in this m715 6cyl engine ? also what was the thinking behind this under powered engine were they trying to get the best mpg gas millage as they could ?? or were they trying to get the best torque from this cu inch engine ??? or were they trying to get a built proof engine that just would not break or go bad ?? I just don't understand why they went with such a horrible engine ??? I think in 74 or 75 they paid a lot of money to put in a German turbo 6cyl engine into several thousand m715s so they must have thought it was under powered as well . my m715 has 17,000 original miles on it and it has no power it sucks . does anyone think their m715 has enough power ??? I was told where the big issue is the valves and cam but I don't know . so does anyone know if this is true ?? or where do you think the biggest problem is with this engine is ???
