Ok. If you have a 2.5 Liter I4 4 Tech your looking at 94-105 hp. 2.8 V6 Liter around 125 hp. and 4.3 liter V6 anywhere from 160 - 165 hp.
Hope this is helpful

DUH..I should have stated it was a 4.3 from the git go I guessed it was only around 140, great for the flats but not much for driving up hills Thanks..Ken
