I got a '07 with the 4.7 in it and was wondering what kinda mods are out there for it and what all works? Let me know if and what you guys have all done.

Thanks!!

 

There's lots of threads about this on here. Check out the search function.
But just a few are an e-fan, CAI, exhaust, y pipe, tuner, gears, etc.

 

its all a waste of money, if anything my mpgs have gone down, and theres minimal to no power gain.

ive got an AFE intake, magnaflow exhaust, and a superchips programmer

 

Search would have brought you this list I made

NO on the throttle body spacers. They are meant for a carburetor motor. I would recommend

1. Ported Throttle Body

2. Cheap things like E-Fan, and a new Y pipe. TMR mod is free do it. (use the search function)

3. Headers, only option is shorties for the 4.7

4. I would then do Superships. I am not sure how much difference you would see being a stick and although they do do SOME motor tuning. They focus on the Trany

5. If thats not enough Gears, (The gear choice will depend on what size tire you are going to run most likely a 4.10 or 4.56)

6.2008 H/o intake manifold

7. Under Drive Pulley

8. Then a Torque convertor

9. Then Ported and polished heads
-While you are doing this you might as well do cams, high lifting springs and all those goodies

10. CAMS
-KRC is now offering full billet cams with LSA ranging from 116 to 106

11. Now that you have a cam and new heads you are going to need a custom tune. I would only recommend one tuner for the 4.7 Hemifever

12. For you custom tune you will need a wide band gauge and maybe a couple others to get the info he will need to tune you correctly.

13. If this truck is still not enough for you I would look into a lowering kit to run smaller tires

14. At this point if you still need more the only option is to leave the world of N/A, and at this point you have 3 options
1. NOS-has been run on a 4.7 before that ran good times
2. Turbo charge, KRC is selling a kit with everything you need 2-3k
3. Supercharge, you will be hard pressed to find one. They made one
years ago for the 4.7 but discontinued it. You will see them come up
for sale every now and again.

Any more questions PM me and I can forward you to real 4.7 gurus.

And the Custom SCT tune can be substituted at any point in time. It will never hurt to jump into custom tuning earlier than needed.

than something on your truck isn't right my 04 4.7 is alot faster than what it was with out my mods .... and since i put my s/c in it has gotten alot more A$$ and mpg's......and i don't feel as they are worth less at all.....and what size gears do you run? that might have alot to do with it....

 

sorry, im just being realistic, sure its helped a little bit, but no where near worth the money. my 71 nova is a fast car, so im comparing the money and power returns with that motor, which is a 350 (5.7)

gears on the truck are w/e came stock

 

So probably 3.55's. Maybe a change to a 4.10 or 4.56 gearing setup may help you.

 

well mdram your talkin about a different ball game then at that comparison....thats 2 diff makes, weight, hp, gears the whole 9 yards.....thats like comparing night and day....mine has 3.92 and they arent bad at all.....

 

I have 4.56 in my 4.7 I love them.

 

eh, just talking engines moving vehicles. i always here guys on here asking how to mod there trucks to be fast, and its like come on now. especially with the 4.7s. the 4.7s are in there to just get the job done. now the hemi on the other hand might turn out some better gains with the same mods.

i can just tell u this, our family's old stock beater mini van will smoke my ram any day, pretty sad...
