As long as the oil filter is not below the oil pan in any way, then go for it.
Well, it does stick down about an inch lower than the pan. The pan is up many inches above the frame crossmember and the filter is at an approx 10 degree angle from horizontal so only a small portion of it can be seen if you look under the car from the front. I figure it will also help with cooling since some of it is now in the airstream.
Great info guys on different filter types. I don't think I will be buying Fram anymore.
But the other better makes also make 4.3 L filters that will work too.
