my 01 4.7 CC came with a 9.25 rear

 

both my 07's came with the 9.25, club cab has regular 4.7 with 3:55's, the quad has the HO motor with 3;92's,

 

my 01 4.7 cc has the 9.25 with the Al driveshaft

 

my 03 as well...the only 8.25's ive seen were on the 6 bangers

 

My 00 QC 4.7 auto has the 9.25.

 

ok, this is going to make me look like an ass, but I had to check, I do have a 9.25 in the 4.7. I've see a on the sticker on the axle right behind the drum had 8.25 on it. But its a 12 bolt cover that I never counted before today. I really feel stupid as hell, I thought I had a 8.25 all this time. Well time to send the gears back and get the right ones

 

..... Well time to send the gears back and get the right ones

That sucks!:funny:

 

That does suck!

SPEED SAFE, AIR RAM

 

Headers are going on Wed. Will go dyno it again and let you guys know what gains they are good for.

 

please do make a new post so we can find it

 

let me know how everything on your truck goes. i just put my 4.7 away a couple of weeks ago and i only have a few upgrades to go for mine. mainly the cams and brake upgrade.

 

*UPDATE* Ordered the Sharadon Stage 3 valve body tonight, and my Auto Meter guages and Wideband Commander all came in today. Killian called today and said he had gotten my head porting done, so I just need to send him my valves and stuff so he can do the valve job and set up the springs, etc. Going to hit the dyno this week and report back to you guys. Hope to get over 200 hp this time at least!

 

sounds killer man, way to be the pioneer:mullet::mullet:

 

i have a stupid question and hopefully someone can answer. i read somewhere that the 4.7 that went in the 05 dakota is different than the older 4.7s. is there any truth to that because i have an 05 SLT CC that's begging for me to go under the hood. i haven't been able to get a straight answer anywhere else i've asked, so i'm hoping you guys can help me out. and if it IS the same 4.7, then i'm going to drain my bank account. also, where is the sticker for me to check my gears? thank you all in advance for your help.

 

I know the engine computer is different from 2004-up because the Superchips program runs up to 2003. The compression ratio changed from 9.3:1 to 9.5:1. HO cams are still one of the most cost effective performance mods, along with air intake and freer-flowing exhaust (especially the Y-pipe). BTW, Air Ram has the Superchips 3715 for $299 at the moment.
www.allpar.com/mopar/47.html is a good info read on the 4.7.

 

I thought the 4.7's were pretty much the same up until this years model when it jumped to 300 hp, but I'm not positive on that. The sticker to check what gears you have should be stuck to the bottom of your glove box.

 

word, i'll have to check that out in the morning. i'm changing my pulleys as soon as i get my tax return. will i notice that much of a difference if i change the stall converter *i think that's right* when i change my gears? by the way, i have an auto.

 

I didn't change my gears and converter all at the same time, but each of those mods by themselves were far and away the best mods I have done to my truck. If you do them both together at the same time you will notive a VERY nice kick in the ass from them.

 

Shoulda got a manual

 

.....

anyway, thank you all for the information.

 

Ordered HO cams last night

waiting on UD pulley GB

by HO cams what do you mean? i read somewhere that the cams from the high output 4.7 drop right in.

check out this link, if you scroll down it talks about the HO cam and intake upgrade for the 4.7.

hmmm...do i play it safe and upgrade my 4.7 or do i follow my cousin's crazy ass idea and try to stuff a 360 in my dakota. lol

 

360 in an 05....:snooze:
I'd say go HEMI!!!:drive:

 

the hemi was my first plan of action. then i started thinking about hood clearance and engine bay space. i dunno, i'll prolly just build up my 4.7 while i save the cash for the new motor. with overtime, i can have the hemi/360 in 7 months tops.

 

Is the (new) hemi alot larger than the 360?

 

You could always put on a nice cat back. My 3" gibson really woke up my 4.7, and it could be used behind the hemi later!

 

if the hemi can be put in a gen III dak i dont see why it wouldnt go into a gen IV. unless the 360 is really built, i dont see the point:huh:

 

i just have a thing for the 360...always have. when i had my intrepid i was toying with the notion of dropping a 360 and converting it to rear wheel drive til i realized what a piece of crap it was. hemis are nice and everything...but clast loves the 360.

You could always put on a nice cat back. My 3" gibson really woke up my 4.7, and it could be used behind the hemi later!

i'm just gonna build up my 4.7 and store it in case my new engine blows up.

 

yeah and with the 360 you would have to get a different tranny.

 

If you put the 360 in it, say goodbye to any resale you once had.

 

yeah i already knew that. this is about personal satisfaction though. come to think of it, i don't think i've ever sold any vehicle i've owned. they just died on me.

 

Be different, swap in a 6.1 HEMI

 

hey when you guys talk the y pipe on the exahust you are just talking about the junction between the right and left sides of the engine right...where they meet on the passenger side of it?...

 

yes.....that would be it
