my friend has a 1999 f-150 with the 5.4 engine.. he has intake, full exhaust, headers, programmed, lowered, and a few other odds and ends... regular cab short bed. around what time would it run in the quarter? also has 4:10 gears

 

after reading on a few F150 forums.. id guess anywhere from a 15.5-17.5 depends on where at in the Country your located

 

17.0+

 

Those trucks are sllloooooowwwwwww.

 

I know it will run faster than that. cuz a bunch of us guys had a quarter mile market out on a road and it would run 97mph through that! FACT

 

by looking at the speedo and marking it when you cross the paint on the road?

take it to a track and see.. you can guess, speculate, think and hope all day, but a time slip will get you everything you need to know.

 

where you located?

 

My truck will trap 86mph on 1/8 mile track. FACT the modular v8 on the 1/4 15-17 seconds, unless you have a f150 lightning.

 

yea even the lightings are pretty sluggy stock..
my neighbor has 02? lighting w/ headers, stall, some kinda upgraded pretty super charger, lower pulley, and upper pulley ~16-18psi , dyno tuned.
he went .1 faster than me and i MPH him bad with me on all terrains

 

FACT: Fast trucks wear bowties
