Ok stupid me went in on this project with blinders on but I bought an engine for my car that came out of an F150 that orginally came out of an 86 mustang. regardless I had to change out the f150 parts(intake,oil pan, sump screen, etc) I now have the car running fairly well in the mustang but discovered the firing order is for the f150 not the mustang(as I said learning) and if I change to the mustang firing order the car runs but not as good as the f150 order. So now I want to know what the differences in the camshafts are. is it different lift? Different Duration? if the firing order is different what will I need to change to make this engine work for my needs? All I want is stock setup nothing exciting Help !
