i just picked up a lightning-swapped 99 f-150. it's extra cab with the small doors that swing open in the rear, i'm not sure what the technical name for that cab is 
anyway it's got some 22s on it and it looks good, but i feel like i need to step up the gearing some, as it wants to do 70 on the freeway way under 2,000 rpm, and it's hard to drive around town without getting into boost as it's all load and no gear. as far as i can tell, the rear end has a 3.55 set in it now, and the tires stand right around 31 1/4- 31 1/2" high.
i was thinking a 4.10 should do it, but a shop that's going to have their hands on it was saying they'd recommend a 3.73 because 4.10s might be too buzzy. what do you guys think? anyone with a geared 22'd lightning or hd truck?
thanks guys
