The 5.9 in that era was sold in different ratings for different duty cycles. 100% power heavy duty applications were 160 HP and lower (some as low as 120 HP), while light duty applications like RV and pickup trucks could be rated 190 to 230 HP.

So yours could be anywhere from the highest HD rating (160) to the highest light duty rating offered (230). Cummins will know.
