Should I find one for cheap for my ol d-100, I was just wondering what you can do to the 4.7? Is there any kind of aftermarket support for these engines yet?
BTW, I spend most of my time over in the SRT-4 section, but I'd thought I'd ask you experts for info on this issue.
Thanks.

 

the 4.7 has limited mods. Intake, exhaust, jet chip (if you wanna waste yr money), headers, not much else.

 

They actually have a supercharger for the 4.7 if you want to spend money on it.

 

theres plenty out there for us 4.7 guys, just wish i had the money[:-]

 

The only thing i haven't done is the headers (don't want a supercharger)....what else is there?

 

well its not only things for under the hood, gear for the rear can give you alot of 'git up and go. aluminum drive shaft, throttle body, i'm not sure if they've made a performance cam yet for the 4.7...do a search and you'll get plenty of hits for "4.7 engine mods"

 

i've considered the rear end gears.....but i'm afriad of what it might do to my top end acceleration. I do ALOT of freeway driving....so i needs my top end!!!!
Already got the fastman TB...so thats done.

 

Yeah, if most of your driving is highway i wouldnt go any higher than the factory 3.92's unless youre going with a lift and bigger tires, do you know what gears you have?

 

the stock 3.55

 

dude, get yourself some factory 3.92's with the limited slip...have no idea how much of a difference that will make and it wont hurt your mileage
