Hey Tripper2, you got two of the smarter guys in here talking to you. Good thing I showef up, I can help dumb this down a bit.
do you know your VIN number? These guys can help figure out what your truck SHOULD have in it. They are assuming that you have the original engine in it.
You can find the Vin on your registration, or on a little tag on your drivers door or on the door jam.
I am gonna go out on a limb and bet it is still a 351m since it still has A.C. Forget the vin. Count the valve cover bolts. 6 means it is a windsor class engine. 8 makes it a 351c 351m or 400. Unless it is something exotic like a boss 302 which would use the canted valve cleveland heads. Doubtful
