I have a 1985 Ford F150 XLT Lariat. 351W with a 4barrell carburator. I have an extremely low geared rear end in my truck becuase the guy who had it before me pulled a 5th wheel with it. I was wondering what the highest geared rear-end was that came in these trucks so I will know what to look for. Any help would be greatly appreciated. My truck sucks gas and doesn't accelerate past 50...help please. Great acceleration up to 50.

 

3.08.

My 79 has 3.08's in it with a 2BBL windsor. It's still pretty torquey and if your nice to it I can get 16. It acclerates well, can keep up with my buddies EFI 300\5sp with 3.55's.

later,
Dustin
