what will be a better upgrade in my truck

long tube headers

or gear ratios from 355 to 411
??

 

i meant 410

 

depends what you're going for

 

Headers will give you a performance increase hp/tq wise. Gears will help you regain what power you lost if your lifted, or it will give you better towing gear if your stock height because you'll have more low end power. More info on your truck and your intentions for it would be helpful.

 

my truck is 5.4 with electric fans, intake, pulley, exhaust.. and my next mod is one of both. and my intentions are to hit a 14.0 in 1/4 mile

 

then get headers first, if you really wanna hit 14's easily throw in a 75 shot of nitrous

 

headers will help me get there faster?? n.o.s. i want to get there all motor.. then hit the juice

 

I'd start building that motor if you plan on running nos. And while your doing headers I'd do a set of hi-flow cats or just delete yours completely.

 

thanks for ur help... headers it is then...

 

id rather have gears. you have to be tuned for the headers to get real gains from em

 

True, but he's gonna need a tune anyways if he wants to hit 14's.

 

You need a TB spacer and warm air intake (ebay 14.99 special) if you want to hit 12's

 

is this truck a short box regular cab 2wd? Even if it is you will probably need both to even come close along with custom tuning. Also stepping up to a 4.1 ratio will lower your et more than long tubes will

 

long tubes with a custom tune no doubt. THEN gears, THEN blower.

 

I say the gears. Headers are not gonna do much.

When my buddy did long tubes on his 2000 F150 I think he gained 16 hp, but he already had no cats before the headers.
