PI heads...did they put them on the 4.6L triton truck? :shrug:

If so, what year did they start?

Are you sure about it being 99 on the trucks? I know they didnt start going with PI heads on CV's till 01.

Our 99 Expo to my knowledge was a PI motor. It had about a 25hp increase over the 98's as far as ratings go. Only makes sense to me since all the 2v V-8 heads were suppose to be the same
