Hey guys, My car is at the shop I'm adding bolt on's on it. BBK long tube 1 3/4 headers, BBK short H pipe. BBK aluminium pullies, Billet steel fly wheel, King Cobra Racing Clutch and BBK adjustable cable.

The car has on already 373 gears, Pro 5.0 shifter, A/C delete Ford Racing tune up kit, BBk cold air, ford racing oil breather and full suspesion, cobra R rims with Dunlop ZR tires.

How fast do you think I should be running with all that on?? and how HP is added??

I will try to post my car pics soon!

you will probably have less hp than stock, your headers are too big for a stock motor, and none of the other mods add hp.
I say around 180 rwhp.
you could run mabye a high 14 / low 15 second quarter mile.
that exhaust will slow you down,
the 1 3/4 longtubes would benifit if you had a high compression 347 stroker, or a 351/408/427 stroker.
you will loose all the exhaust velocity killing your low end torque.

I'm not much of an expert on 5.0 but I do a lot of research before modding my car. Recommened for header upgrades are egual legnth and the long tubes. The 1 3/4 long tube headers don't make you lose power they help you gain. I know what you mean though when you say I might lose power. The long tubes that would make me lose power to are the 1 5/8 long tubes. The 1 3/4 long tube is more of a street header and the 1 5/8 is for some serious HP.

so how would the smaller one be for serious hp

and the bigger one be more of a street header?

I have a 306 with about 400 rwhp and 150 shot of nitrous. My motor ran better with 1 5/8 headers, AND 2 1/2 exhaust. I actually lost .30 in my 1/4 time with 1 3/4 and 3" exhaust. So needless to say, I went back with the smaller exhaust... Synyster
