his has 3.73's, the engine is out of a 99 truck, it is definatly the lower rating. the origonal never had the oil changed, he bought it blown up and we put a motor in it, has the smaller heads, smaller intake and all. anyway you look at it i dont think i should have lost to it......... lot bigger, alot heavier, not much more power to warrent a victory. but its a mute point, it wont happen again...hahahaha

 

My Excursion is strong but I don't think I can keep up with my Durango now that I have 4.56:1 gears in it.

 

lmao, i bet it pulls hard with that much gear in it, got 4.30's in my charger and that is pretty stout. 4wd launches with 56's would be sure to make your neck hurt

 

Mine's 2wd but it still barks into second every time.

Dan at www.thefastman.com has a 52mm bored TB for the 5.9L, a 50mm for the 5.2L, and a 68.5mm for the 4.7L and he does a better job....IMHO.

 

+1000000000000

talk to dan and he will take care of you

 

he is half the cost too, i will be getting one in the near future, have to do headers first since i have 2 busted bolts on the right rear. i figure if i have to pull the manifolds there aint no way in hell i am putting them back on

 

That's ok, I'll stick with my 8.0L (V10 488cdi) with it's 300hp and 450lbs torque.

 

You'd be surprised how equally matched both of our trucks are both in pulling power and mpg.

 

I was wondering, what is a good spark plug to use for the 4.7L engines? and also what is a good fuel system cleaner to clean out the injectors and everything else? I didn't know if there was a brand that people on here liked the best for these engines.
