4.7 mods

The Assassin · Sep 13, 2011

OK...so I've dome the intake...exhaust...gears...and programmer. Going to look into cams headers and possibly a larger throttle body. Does anyone have any other mod suggestions? I had been thinking about a full motor swap but I really don't have the money for that.

2008 intake swap seems to be good for some hp as well as what you have listed.

HO cams can run off superchips, but anymore agressive than that and you will need custom tuning with a diablo or sct, so you will need a wideband for that.

A torque converter will help recover some of the driveline losses.

Superchargers were talked about for the 4.7, but very few were made. You could always get an STS turbo kit, but then you will need custom tuning again.

Ported TB helps throttle reponse on the 4.7 a good bit. I have one by "The Fast Man" on my Durango, it really does help.

Great info! I'm thinking about the 08 intake swap. I have also considered a one off STS kit. And other than the HO cams, I wouldn't know where to find anything else more aggressive these days.

Most noticeable mods have been the Superchips and the gears.

Nickxxxr · Sep 13, 2011

What gears are you running? You run 37s right?

Nickxxxr · Sep 13, 2011

I see i was planning 4.56 gears when i get money. My next set of tires will be 35s and the set after that ( i hope) will be 37

I know, with KRC being bought by WPE and no one can get in touch with them the options are limited. If you can find someone that has a KRC cam card you may be able to get comp to grind the cams for you.

You could alway swap in a hemi, I have seen used 5.7s for around $1500 and 6.1s for about $3200.

I don't know if you get on "the other forum", but there is a guy selling HO regrind 206 cams in the classifieds.

And another selling a 2008 intake

I had thought about that. But finding all the wiring and what not can be a PITA. Plus, I have to figure out how, with having a lifted truck, to get the motor out.

I'm not sure how it would be, my only engine swap experiences have been with old chevy sb and bb v8s that were carb'd

The Assassin · Sep 13, 2011

Any thoughts on an E-fan?

ramin44s · Sep 13, 2011

i want to see a sts turbo on ur truck! that would be pretty cool but i think airram has 206 and 212 cams on his site for the 4.7 also

07BlueRam · Sep 13, 2011

What is the difference between an 06,07 TB and and 08TB bc I would like to get a little more power out of my truck. Will it just bolt right in stock location?

ramin44s · Sep 13, 2011

^ you have to buy adapters from what i have heard.. they sell them on airram.com

Who said you need custom tuning for more than a HO??? My brothers 03 Dakota has 218/224s, 08 intake, JBA headers, 2 1/4" duals and idles/runs great on Superchips 91 octane programming. SCT would be better but not needed. Even my Hemi runs pretty darn well on Superchips 91 4.7 programming. The only tuning on the truck is a Split Second Cam Tuner at the moment although we played with a PSC-1 on it.

FWIW on the 06+ 4.7 engines with EGR if you do the 2008 intake, you will need the 2008 EGR valve and pipe.

It is not just the TB difference on the 08+, it is the intake manifold. the 08+ 4.7s had some other changes as well to get from 235hp to 310.

Jeff, I don't know that there is a difference with the throttle body. I know that the intake manifold on the 08's offer more power than the 06-07.

The 08+ 4.7 has a DBW throttle body similar to the hemi vs the 99-07 style cable operated unit. The throttle bodies have a different bolt pattern and gasket layout. The 08 intake has to be run with adapter plates to make the older throttle body work.

The 06 and 07 trucks need the 08 EGR parts or else the manifold will hit the 06-07 style EGR valve.

The heads, pistons, connecting rods, cams, intake, and tuning are different on the 08+ engines. The 08 rental truck that I drove had a converter that stalled around 2,800 rpm in it as well.
