So i found these shorty headers for my 4.7 (looks like a decent price too), and just wanted to know, potentially what kind of power i would be gaining... If i remember correctly, shorties give hp while long(ies) give more torque, but would getting shorties reduce my current torque output?

you wont be gaining any power. 4.7 manifolds flow within 2% of headers. the only logical reason to put headers on a 4.7 is if you want a better exhaust sound or if you're boosted. also, those are only painted... they'll look like rusty pieces of crap within 6 months.

 

yeah but for that price i would just deal with the rust, if you go with shorties and no cats that little 4.7 will still sound pretty gnarly. if they rust out in 3 years, whatever, theyre cheap, get another set. maybe by then someone will make an affordable priced set of LT's for your motor.

 

throw some high temp paint on them before your drop them in for a little more piece of mind

 

I woudn't even spend the money on headers unless you where to get longtubes.. not worth it...

spead the money on a better Throttle Body or H/O intake Manifold... or H/O cams..

 

lol

go with what user said...better in the long run

 

too bad no one really makes anything for that crappy motor. HO cams would be the way to start i would think, followed up with an intake manifold and TB. but again, really, why even try with that little 4.7.......

 

if you still have that damn truck in a couple of years in gonna drive to chicago and whip your ***!!!!!!!!!!

 

The 4.7 is a better motor then the 5.9. We just have more aftermarket to make it Better then the new **** coming out... sadly the new v6s coming out have MORE HP and almost the same torque as our old 5.9 v8s.

So leave the 4.7 guys alone. Its a v8 thats all that matters pick on the 3.7 and 3.9 people... and the people with the 4cyl... dont even bother with them.
