my 04 f150 XL heritage(03 style) with a 4.2L V6 and a 5spd manual 2wd reg cab long bed with K&N cold air intake only went 9.58 seconds. i could have gotten it quicker i think if i launched better but maybe only 9.3 seconds. i have a video of it on youtube going to 100 and also the 9.58 0-60.
i no longer have it, i got a 08 f150 XL shortbed V6 stick and its geared lower and i havent gotten on it but i think its gonna be slower because of the gearing.
i dont know the 08's gearing(has towing package) but i found the order sheet for my 04(no towing package). the gearing was 3.08 and 1st topped at about 40mph, 2nd-65mph, 3rd 90mph, i dont know 4th or 5th but i had it to about 105mph. the 0-60 of the 4.2L V6 is 10.2 seconds stock, the intake adds a lot of power to the 4.2L and the gas mileage is pretty impressive. went from 18.9mpg average, to 19.9 with a K&N drop in filter to 22.9 with K&N 77 series intake. and the intake also sounds SOOOO much better when you get on it. it sounds like a small V8. and also it made my V6 be able to kick the rear end out about a foot while shifting into 2nd and spin tire for about a quarter of a second. and my 04 weighed 3800 or 3900 LBs

just found a printout i had out of 37 pages of 0-60 and 1/4 mile times from a website. website is mostly cars but has few trucks on it. it had an 04 f150 4.6L at 9.9 0-60 and 17.4 1/4 mile but it does not say the details of the truck.
