Thanks widow I was looking a some of the mods folks have done and I'm itching to get the money to do some of this. I have heard of this mod before just never understood it.

 

1998-1999 the 5.2L and 5.9L radiator cap was on the left side and on the radiator.

In 2000+ they reformatted the radiator and fan shroud to include the washer fluids and coolant reservoirs, they also included a electric fan. The radiator cap was moved to the right, on the upper radiator hose to be an inline instead.


The only way I know to tell the difference between the early same year 5.9L and 5.2L motors is actually looking at the engine tag. I don't know of any difference visually.

The Throttle Body's are casted from the same mold other than a different bore. The 5.2L was 2mm smaller from what I've read, but I have never confirmed that personally with a measuring device, but I have seen them and that is what it looks like.

 

so theoreticaly i could turn my 5.2 to a 5.9 by boring out the cylenders? and putting bigger pistons in?

 

Yeah just take the cam from a 5.9 and bored it out and use 5.9 pistons.

Other than those I believe they share the same block.

They share the same block. The stroke is different as well.

 

Speaking of Ebay CAI's... Are there any brands that one should stay away from? I am looking into getting a CAI so I am curious
D- 02 4.7l 4x4.

I was thinking of this aswell - K&N 77 Series High-Flow Performance Air Intake

thanks.

 

K&N is more expensive but it is designed perfectly with the heat shield and everything so you just install and you're good to go. The K&N is what I have and the only reason I'd recommend anything else is because it's so expensive.

If you're willing to fork over the money for the K&N, you WON'T be disappointed!

 

thanks widow! im thinking on it...
what do you have .. like model..

 

Mines going to be a different model number than yours because I have a 5.9 block and yours is the 4.7 engine. I know mines the FIPK Cold Air Intake.
