You can do 13s NA, though you're 4x4 will present more of a challenge.

why do you think the 4x4 would present more of a challenge? Are there reliability issues from the 4x4 system when you start making some real hp? I'm thinking HO cams/intake swap. Obviously the 4x4 is dead weight further down the track, but off the line i should be able to hook like a banshee. Look at parish's truck, that thing just scratches and bites!! Do you guys think that the transfer case and cv shafts would hold up to full throttle launches when i am making 300-325hp? I'm just looking for any known weaknesses so that i know what i am getting myself into before they happen.

thanks

4x4 launches are nice, but not any better than a 4x2 with slicks or DRs. On the street nice, but on the track the added weight plus the raised height hurting aero, it'll present more of a challenged than a 2wd.

Go with a 70mm F&B throttle body, CAI and some free flowing exhaust and you'll be making some decent power. If you don't mind sacrificing some low-end torque you can go with larger cams. No matter what you do - you will need to make it pull both rear tires. If you go with more aggressive cams you should probably go with a set of gears also.

The 4.7s do in fact have some potential....

right now i have an 05 4.7, with a 7 pipe exhaust system (flowmaster), and an air intake (k&n fipk gen 2). my truck is not slow at all, although it could be faster..it even competes with a chevy 5.3 extended cab, even wiwth the wewight difference..there is a lot of potential with the 4.7, it just costs money lol

Go to www.airram.com and talk to Nick he has a 02 Ram quad cab with a 4.7 that is running 9.1 in the 1/8 mi, and it is fixing to get faster. He currently has an Air Ram intake and scoop, HO intake manifold, HO cams, Fast Man throttle body, ASP pully, E - fans, 4.56 gears, headers, and exhaust. He has a set of Fast Man heads, KRC cams..cant remember which ones off of hand, and a converter about to go in. He is pushing alot more weight than you and putting down respectable #'s. Hope that helps

I think i will be going with the HO cams and throttle body and all the supporting goodies to go along with it.

One quick question, do you guys think there is more potential with a 99 silverado with a 4.8, 5spd, 4x4. I know that this combo is kind of rare but i have seen a few of them for sale lately in the local paper. They are going pretty much what i paid for my dakota. I betcha i could trade my dakota almost straight up for the silverado. What do you guys think? Or do you think with comparable work i could get the same numbers out of a 4.7 and 4.8?

i am torn, i like my dodge but if the chevy has more potential than it is kind of obvious who to pick. Again, what do u think?

Trade it in for an R/T, youll be much happier. But I wouldnt advise a wet nitrous kit on teh 4.7, the manifold is not designed to carry fuel, and sooner or later, a back fire will blow it to smitherines.

Unless you do direct port, no nitrous.
