Hmmm.. this is wierd. I am sure it was a 5.4 because my bud was talking about the liability and warranty issues with the transmission. And why would a 4.6 come with a 9.75? I know it was a 9.75, it is not hard to distinguish it from the 8.8. I would be skeptical too but I actually saw it.

 

x2 sounds right. Maybe the dealer put a 5.4 throttle body cover on it

Or could it have been a 97-99 Light Duty 250 with 150 badges on it?

 

HI!... The factory would of not done this. Trust me I have been in both the OAKVILLE truck assembly plant and the WINDSOR engine assembly plant. They are not equipped to do this. What probably happened was the dealer ordered a "97" F-150 extended cab with the 5.4 which came standard with the STERLING 9.75 rearend. Then the dealer probably had their techs do the 5-speed manual swap in their own shop. This is the only way this would of been done. If this truck exists at all.

 

I don't even see the dealer doing that. It would involve cutting holes in the fire wall for the clutch master cylinder. Cutting a hole in the floor for the shift lever. Installing pedals. New Wire harnesses. Removing the Automatic tranny shift lever and installing a new instrument cluster to remove the PRND21 indicator.
