I've been racing my 2000 4.7L 5-spd club cab (amber fire, if that counts) for about a year, now. I race at Commerce, GA at Atlanta Dragway. I've made plenty of passes. I have the 3.55 posi rear, I weigh 300 lbs (I'm 6'-6"), and I usually aim to have about 5 gallons of gas in the tank (gas weighs 6 pounds per gallon). I have a soft tonneau cover, a K&N filter (in the stock air box), and I run Mobil One Synthetic 5W-30. Other than that, it is S-T-O-C-K stock. I leave the tailgate, bumper and spare tire in place. I usually try to launch at 2000 rpm and, because my torque seems to fall off at 4500, I shift there. The best time I have run so far is 15.48 @ ~86~ mph. That's on a cool 65 degree dry day in Georgia in April. The tires are the 255/65/15's that came with the 2000 year Tire & Handling package. The truck has about 22000 miles on the motor, and I run the rear tires at about 30psi at the track. On the 15.48 run, the tires actually bit and I pulled a 2.24 60-ft time. I don't think that the old Dakotas (they weigh less and are therefore still faster) would run better than 14.9 in stock trim with a 318/ auto and a 3.90 rear in a standard cab (see MOPAR Action from around 1992 or 1993).
I guess what I'm saying, is.... Crap on the 14.2 timeslip or not. If it's stock, that's bunk. If there really is a 14.2 on the time slip, it ain't stock.
The other thing I'm sayin is...... Let's all just SHUT UP & RACE!

Ok folks, my 4.7L has been 14.8's many times in stock form. I've seen Carson Henderson (RC 4.7L) run 14.7's stock at VA motorsports park. So there it is, 14.7-14.8's is VERY possible. However, 14.2's, stock?, hee hee, I have to laugh. I run 14.2's currently, with a Custom PCM, air-intake, Mobil 1, Flowmaster, Hoosier DOT slicks, tractions bars, and DUMPING THE CLUTCH AT 3500 rpms! I've run close to 150 passes since October '99.
in order to get the 4.7L in the low 14's, you almost have to dump the clutch at high RPM (unless you have NOS,or SC'r) I'm not so worried about the clutch, the rear end is what scares me now. Believe me, I grenaded a rear end, 9 1/4" rear end, last fall at VMP. I was pulling 1.88 60' times, and it let go. Had to replace the complete assembly, housing and all!! DON'T think these rears are bullet proof ;)
A stock 4.7L truck, with slicks/traction bars can run mid 14's with NO problem. With a K&N filter and slicks I ran 14.4's. added the computer, and Flowmaster, and now I'm 14.2's.

Competition Engineering (slide-a-link) said that I would have to loosen up on the link some when driving on the street. It would still work but not as well - about as effective as slapper bars when loosened. Calvert Racing (Cal Trac) said that street adjustment was up to the driver. It will ride better if I loosen them up some but they have been running some on a S10 with 1/2 round of preload for over 100000 miles with no noticable wear.

Was there any noticeable wear on the driver's kidneys?? I know that Cal-Tracs are the best, but a guy at our local drag strip said that even the Slide-A-Links really stiffen up the ride on his 68 Camaro to the point where he trailers it to the track on Friday nites. Sounds like it could be a bear in a truck (with the light rear-end).

I've had the Caltracs on mine for about 6 months now, their set at about 1 round of pre load, and yea they're stiff!! You only notice them being stiff when you hit a ripple in the pavement, and the tires get light, and slip a little. When the tires come back down, hang on, cause the leaf spring can't soften the axle wrap anymore, its gonna hit HARD. It scared me the first time I felt it, its a serious jolt! But I'll tell ya, its worth it, cause she hooks very hard on the street now. The front end come way up on the launch. I used to be able to nail 3rd gear, and now it just hooks up hard. Also, you should know that when you install the Caltracs, you replace the front spring eye bushing, with a solid aluminum/steel bushing, NO rubber !! This also causes roughness in the ride.
The Caltracs are not "easy" bolt ons either, they required you to remove the leaf springs, press out the old bushing (with a press) press in the new bushings, and re-install as an assembly with the bars,springs, and the rear-end.
I installed them myself, but I would caution the novice mechanic/ do-it-yourselfer, this is a seriuos project.

This may sound odd, but thanks for that insight. HOT ROD and the other magazine guys only tell you how these bolt-ons do at the track. They don't describe what it's like to drive to the office with zero spring rate on the rear end of a pick-up truck. And the other thing- they don't tell you when you can't bolt it on in the backyard with floor jacks and hand tools. So thanks......
I may still think about them, though.
btw, where is VMP? My brother lives in Richmond, and I may come up to see him this summer. I like to race in towns that I visit, if I'm there for the weekend....

Alex, no problem, I agree totally with you, Hot Rod, and other mags make it look/sound easy. However, this installation was pretty time consuming, and not for a novice installer!!
VMP is south of Richmond, about 35 miles south in Petersburg VA. However, my "home" track is Richmond Dragway, which is right in Richmond, at the airport. Only about 15 miles South east of the city, and 2 miles from the Airport. Richmond Dragway has always produced the quickest et's for me, and the entry fee is MUCH lower. Only $9 for Friday nights, and $11 for Sat/Sun race. compared to VMP which charges about $30 !! (VMP facility is much cleaner I must add)
If you're going to be in town, give me a shout, I'll go with ya!

4.7 wins if it manual. Don't know for sure about auto vs auto. I tend to think the R/T but it seems some 4.7 auto owners are claiming they are winning also. R/T is a torque maniac but the 4.7 is about as light as a 3.9 liter becuase of the aluminum heads and composite intake manifold. It also revs out much higher because it's SOHC. 5.9 R/T owners are often critisizing the 4.7 because it's hard to deal with the fact that an engine this small that uses way less fuel can take em down. Hell when you order an R/T you are doing so because you want one mean macho truck the can't be touched. It's hard to beleive some whimpy looking sport could even match up but 4.7 wins out by using technology over brute force.

Jeffster I respect and enjoy your posts here but disagree on this one. I'd say that the manual 4.7 to the R/T would be close, but there is no way the 4.7 auto would consistantly beat a R/T. It would have to be much much lighter to make up for the Hp/Torque disadvantage. A good rule of thumb is every 100 pounds is about equal to 10 HP and results in .1 sec better in the quarter mile. The R/T is lower which reduces drag, the 255/55/17's are actually 1 inch shorter overall then the 255/65/16 which if the both have 3.92 gears the R/T is actually getting a little more leverage on the tires with the smaller diameter, the 17" stock R/T wheels are also better for dragstrip traction then the anything the sport comes with. It doesn't matter how old school the 5.9 motor is when it comes to making the horsepower and torque numbers. An old saying always comes to mind, "there is no replacement for displacement."

Hersbird there is definetly a replacment for displacment. Technology. Motors are getting smaller not bigger yet cars are getting faster and faster. Mustang 4.6 is case and point. I will absolutley take my 4.7 5 speed out against any near stock R.C R/T I can find. Have tried to spar with some of the dozens in Vancouver but they just cruise.
Also you say every 100 pounds equals 10 hp or .1 in the 1/4. I don't know but am willing to bet a 4.7 with a manual ways around 200 lb less than a 5.9 with an Auto. If this is so the 4.7 would have a weight compared 255hp to the R/T and I can feel the power to 5,300 RPM's. The 5.9 drops very fast after 4,600 RPM's. Anyways I am conviced I will win any encouter I have with a stock R/T and will continue to search for prey.

The same technology can always be applied to the larger motor making it faster, and lighter. It gets very difficult to make the smaller motor larger, and then remember the larger motor can always be made larger yet. The 360 can pretty easily be made into a 400, but some aluminum heads on it, or a complete aluminum block and it would be much lighter then a 4.7. The 4.7 is more able to rev because of the overhead cams but if you think the old small block dodge can't rev then you have never seen those same motors turning 9000 rpm in nascar. I agree the 4.7 is great but as I had to get an automatic, the R/T is easily the fastest automatic Dakota. Dodge should have just made the 4.7 a larger displacement motor in the first place but they were trying to improve feul economy and emissions not necessarily performance. I have a feeling the R/T is better then the initial tests the magazines did back in 1998 that got some of those 15 sec+ times. Most of those were on CC and the RC would be .2-.3 sec faster. If a RC 4.7 5 speed can do 14.7 1/4 and the last test I saw of a CC R/T stock was 15.0, I bet the RC is a 14.7 as well. Also the R/T would be easier to launch consistantly to get the same time every time, not 14.7's just with the perfect launch and shifts as the 4.7 5-speed requires. Also the 5.9 is a tighter motor from the factory and gets faster with 10,000 miles on it. I haven't heard that is as necessary with the 4.7, the magazines amost always have a brand new truck with probably not even a 1000 mile break in complete when they run their times.

Hersbird, like I said earlier, if you dont believe that a 4.7 is faster than a R/T, drive one (R/T). A dealer will be quick to give you the keys for a test drive. I was seriously looking at R/T's and would have bought one before I drove them. They were no comparison to my 5.2. Granted, they were brand new trucks when I drove them, but a 2 second difference in 0-60 times is not going to be made up after the "break in".

Well I did drive a R/T before I bought one, the parts manager's 99 CC R/T. He had done some mods but it was very fast, I never did get full throttle on it. He said it has run low 14's and he's got only Mopar parts in it. (computer, exhaust, headers, air filter, and torque converter.) He says some slicks are needed now as it easilly will overwealm the tires. If that's all it takes to make a CC go low 14's then the RC will go 14 flat with the same mods. Will computer, exhaust, headers, and air intake make the 4.7 go 14 flat? I kind of doubt it. I also had a RC 5.2 auto LE Dakota in 93, it went 15.8 pure stock with a passenger, and I was able to run 14.8's with a couple of mods. I'd hope the R/T stock will go about that 14.8 and low 14's with a couple of mods, I will be happy there regardless if somebody else's truck is faster or less expensive.

Peolpe often say it will go X fast yet have never run there truck. Mine feels like it does low 14's but I know from all the posts I have seen I can expect around 14.8 stock if I get a good run on a good day which I know is faster than a stock R/T. I love my truck regardless of what happens when an R/T out here finnaly runs me. Most are stock and I feel confident I will take em out.
