NOT a Ford guy but!!!!

Thanks for all your info. yes it has 3 on the tree. i do have a engine setting in front of the truck. it's a 1989 460 with an auto trans this engine came out of a motor home that my dad bought new. it has around 38K on the engine not sure I want to go that way or not,it was free.:cheers:
this truck is very clean for it's age.

Go with the 460. By 1988 they were EFI accept in large chassis. If it is a carb motor your good to go, it not, let me know and I tell you the difference between the two and if you want to add some poop to it. I can point you in the right direction for information.
