hi i got a 1998 bone stock 4 door 3 speed automatic p.o.s. and i took it to budds creek today. all it has is a filter. nothing else. it ran 16.92 and 17.0's all day. i ran it 11 times. remember 3speed 4door 2200 engine. what do u think i would run with a header and full exhaust.
probaly around 16.5

Im a Xbox 360 fanboy...and damn proud of it!!
wow, my 2 ton crown vic ran that stock.... seems kinda slow

Got the same exact car, 3 speed, 98 4 door, and alot of work (comparatively), and i doubt i even get in the 16's.
10.2

you'll prob hit 16.6-16.7 if youre lucky
wont notice much of a diff, but give it a try
