HO had a freer flowing exhaust manifold, a larger throttle body, same cam through 95 or so, different head intake port design.
To sum it up, it was a huge and successful marketing ploy by Chrysler and the legend lives on today. The HO put out 8 HP more than a Renix and the same amount of torque. All the HP was at a higher RPM.
