What do you guys think this will run like 392 CID magnum mildly ported heads, back cut and polished valves, 1.7 mopar roller rockers, hughes 1110 springs, 1 3/4 full length ceramic coated R/C performance headers, 3 inch dual exhaust, hughes air-gap intake, ported stock throttle body, 10.2 compression, .038 quench, stock R/T Dakota cam  , 44RE, stock high stall converter, 4.56 gears, 460 for injectors, SCT tuned computer. Just a bunch of stuff I had laying around the shop. Think it will make a lot of TQ?  It is all going in a regular cab 99 R/T dakota with a couple hundred pounds removed no AC or PS.

FYI...The stock Dakota R/T cam is the same as a stock Magnum cam, I'm guessing you will be weak in the intake side with the ported TB, who is doing the SCT tuning?

Yes and no, there is some confusion about the "R/T" cam. It is bigger than the 93-99 regular 5.9 cams (and there were at least 2 versions of that cam that I have found)but in 2000 all 5.9s got the "R/T" cam. The 318 cams were better than the smaller common 5.9 cams, they had more lift and less duration. I have about 20 cam cores waiting to get re-ground when I get a little $$$ saved up. I will probably let a local company do it, they have a chassis dyno so I would think they could get it closer than someone guessing over e-mail, maybe I am wrong  It will start off with just a mopar performance computer I have because it is a "free" build with parts from around the shop. It will be weak in a few spots not just throttle body, I just bought some land and have zero $$$ till I pay it off or I would get a re-grind at least on the cam  I just want to get my truck running.

Dakota R/Ts came with a stock 5,9 Magnum motor, with a stock Magnum cam and stock Magnum heads.
The 5.9 Magnum motor in my 98 Ram was identical in everyway to the motor in my 01 Dakota R/T

Dobe Dave,
yes, you are right, a 98 Dakota R/T had the same exact motor as a 98 Ram 2500.
I think what Rod Dave is saying, is that somewhere around '01, ALL production 5.9s got a slight change in the cam specs, netting a few more hp...but this change again, could be found in every production 5.9, from a Dakota R/T to a panel van.
the misnomer is when people start calling this slightly hotter cam a "R/T cam" like it's something special from MP, when it's JUST a generic, production line cam from a certain model year.

Next thing you know, you guys will be trying to convince me that my 69 440 magnum heads are identical to the ones off my grandma's 383 2 bbl station wagon!
I don't usually race small blocks...but when I do, I prefer ones with a big block torque curve...

The cam's part number changed in 2001, but did the specs really change? Never heard that before, I could drop my 01 cam in my 98 for some more PAH. Found this...I guess the cams did change a little over the years for emissions. "Well, I just got off the phone with the Ram/Magnum tech-line. They said that the stock 360 cam varies a little from year-to-year as the emissions requirements get tougher. They said they didn't have the specs for the 2000 360 cam. They said, however, that the cam specs on the stock one they used in '98 360s is 264 deg. intake duration and 274 deg. exhaust duration. The lift is .410/.410.

That is still the old 360 2bbl/TBI spec,  the R/T cam (I have 2 of them on my desk right now I personally pulled, a 98 and 02) both have .270 IN lobe and .274 ex lobes, an 01 5.9 van cam is the same, a 99 Ram cam is smaller than a 99 R/T, I don't remember the exact numbers but I can pull one out of my stash and post it up. My degree wheel is MIA so lift is all I can check right now.
In retrospect I should have just said it was a factory cam so every one would not get their panties in a wad. I do not expect any huge gain from the best factory cam to the worst, just happened to be the biggest cam I have sitting here.
To get rid of the PS I will just run a loop from one side of the rack to the other, just like the factory did on the earlier dakota 4 cyl. Then ditch the pump, brackets and old lines, install a really short belt and there we go.
I also have an 01 bumper assembly that is a lot lighter than the 99. Trying to lose as much weight as possible off the front so I can still turn the wheels 
As for the premium fuel only comment, I had a zero deck 318 magnum with a stock cam and thin headgaskets, came out to 10.0 and it was fine with 87 in a 99 ex cab ram with 3.55 gears and real tall tires, you can make a very detonation resistant set up with the magnum head VS the dinosaur open chamber LA junk. Even if I have to run premium the MPG increase from the higher compression usually offsets it or close.

I don't know how much the pinging and detonation issue that resulted in the "death flashes" were because of leaking belly pan gaskets vs actually needing less timing - but my previous experiences with higher compression, stock cams and regular fuel weren't very encouraging. I certainly don't know for certain where that threshold is with your setup - but if it pings - you know what to do.
Right on Duner,take a very restricted timing curve and just kill it some more to fix the issue. LOL typical Ma Mopar.

Just an update on this project, it ran great even on 87 no pinging in my dakota, it was like the gas pedal was an on/off switch for burnouts! it is sold to a guy now and is in a 1/2 ton 5 speed ram and runs awesome in there, says he drove almost 600 miles on one tank of fuel to boot.

SCAT cast with mallory to internal balance it ( I bought it used with the weight already in it).
