My dad bought the truck for the whole family but more for me as a grad present a couple months back. He took it to his buddy at ted britt who tour into it and noticed the old motor was trashed so he talked him into putting a brand new one in, which was a brand new 351W ford racing crate motor....not positave on the specs but I have all the info filled somwhere. The tranny is still the stock tranny which was rebuilt the same time the motor was replaced. I forgot to mention that the whole brake system is brand new also. The gears are stock, not sure of the ratio. It has a 6 inch skyjacker lift kit with 35x12.50r15 bfg mud terrains, and some pacer true bead locks. I just had a custom exhuast system made for it, dual side exit with a super 44. I just put in a new sound system also, alpine type r's up front and 2 amped polks behind the seat. Anymore questions let me know.
