Message:
my truck. 99 RC 318 dak. cold air, mopar intake, cam, headers, full exhaust, bored 30 over, mopar pcm.
vs.
00 r/t CC with full dual exhaust, no cat, and k&n cold air.
even though i had all the mods and less weight the guy beat me!! wtf!@! it was prolly by a truck length. i say it has to be the 392 gear and he had smaller tires. there is no way that that 360 has more ponies than my 318.
he dynoed his at 245HP and like 330ft.lbs.
i always just guessed mine was about 265 to the wheels. you guys think a 410 IN THE rear will help me out? by the way i can top it out in 3rd at 105. 4th wont go anywere.

I think you should quit guessing and get it dynoed. Getting your truck up to 105 doesn't mean a thing. Most any stock truck should be able to do that. Also, it's not how much "stuff" you have on it, it is how it all works together. Be a little more specific. For instance, we all have a "cam."

I've had my truck up to 115 many many times back when I used to constantly do stupid sh!t on the back roads and it's just a V6...like N56629 said, that doesn't mean a thing.
I would say it's probably either the gearing...if it's your daily driver, 3.92's would be a smart choice to help keep semi-decent gas mileage. 4.10's will prolly hurt mpg considerably, although it'd definitely race better. OR...you might wanna see if your truck has a speed limiter set at 105...I do recall some Dakotas have them set around there. I usually would hit my rev limiter before I hit any speed limiter which was right around 115 mph (I raced with overdrive off).

As a matter of fact that Dakota 239 V6 I had could do every bit of what the speedo topped out to. And that was with a 3.55:1 gears.

As N56629 points out, you don't know your power until you dyno - all you are doing is guessing. Deeper gears will just about always help in a drag race though. I don't know why some of the other guys are focussing on top speed - in a drag race, the quickest truck is not always the one with the highest potential top speed. It's just the one that can get going quickest. We don't usually see top speed in a drag race.
Lead, follow, or get out of the way

clint,
I've never heard of a 360, with only those mods, dynoing RW #'s that you say. Maybe he did however, it would be tyhe best I,ve ever heard of.
I guess you have an auto, and your top gear won't pull anymore than your 3rd gear at max? That's pretty disappointing to only have 3 gears to max.
If you have a 3.55 rear end, that's probably why he beat you. And the fact that if he has even smaller tha nstock tires, he's now got ~ a 4.10, as you know, depends on how small, etc.
And, if he does dyno those #'s, and I realize he might, than your truck is pretty fast.
Enjoy, be careful, etc.

With your aftermarket? Mopar PCM, your speed and rev limiters are higher than stock. Going "nowhere" in 4th? Does that mean it shuts down, or it just won't pull? If it just won't pull, there's part of the answer...lacking HP. Full exhaust? Meaning full stock exhaust behind the headers or full aftermarket performance pipes? Cam specs? Yes, you need gears. 3.90's and 4.10's are so close it won't matter on street tires, only with drag slicks on the strip. Either set will induce big wheelspin on the street if your setup has any wheaties at all. Minimal mpg difference also. They will help considerably once hooked up, and you'll be able to use 4th, though your top speed probably won't change without better HP in the higher rpms. No way that 360 hit 245 rear wheel HP with just the changes you mentioned.

My truck has the 3.92 LSD in it and that thing hooks up and goes. I know that I can shut mine off in 4th gear and I still have 1 gear to go. 5th gear in my truck pulls pretty damn hard. I heard that with my setup I should be able to barely out run a stock R/T. Is this true?
Finally... a V8. '01 Dodge Dakota RC, 4.7, 5-speed, 3.92 LSD. = R/T Killer.
well at least a stock one

i know 105 is nothing. its actually disapointing because ive been in a stock dakota that did 118 "limiter"
i was pointing out that it couldnt pull it any faster. like i said thats just what the guy said the hp ratings were.
i was planning on giving specs but i didnt expect this many posts.
the cam is a 4.55 lift mopar cam. the pcm has no speed limiter and a 6k rev limiter. i think thats about all it has changed.
i was also just sharing my experience "my disapointment" and asking what you guys think of a 410. the reason im goin 410 is because rustys offroad has all kinds of parts for jeeps. and the chryssler 8.2 is also found in alot of jeeps. so they have a full kit for 300 bucks for 410 gears for the dana 30 front and 8.2. not i have a ford 8.8 with 410s sittin out back that will drop right into my jeep. so all i need is 410s for the front. then the 8.2 gears would be left over for my dakota. if i bought just the 8.2 gears its like 280 bucks. so why not get the dana 30 gears for 20 bucks more. hell i could sell them on ebay tooo. ^^thats what i would say to do to anyone buying gears for there dakota.
i also plan on a stall converter. mopar perf.com said a 2700 from them would be right with my mods. also its only another 300 bucks. so 600 bucks for prolly a second in the 1/4 sounds good.

OH, I didn't realize your Dak won't go over 105mph.
Is it hitting the speed limiter, or rev limiter?
Something does not sound right to top out at 105.

Same old story... Trying to take a 5.2 (318) and
turn it into something it was never meant to be.
By far the 318 was the best little work horse V8.
It never had tire ripping horse power BUT it would
out pull (all day long) a heavy trailor or fully
loaded truck over most larger V8's.
Clint282cc, start with a 440.. Now you have
a good starter engine to modify.

440! That's old school bay-bee!
if you want to buy one ready to install, check out indy cylinder heads
http://www.indyheads.com/
They made the 440 that went into Sgt Rock, the 41 Power Wagon Stacy built on Trucks! for the memphis belle restoration project.
the 440 is a nice fit inbetween the cummins, hemi and magnum.

its not a speed limiter because the mopar pcm dose not have one. once i shift it into 4th it just sits at 3500 and wont go faster. in 3rd i can wind it out to about 5200 and thats 105-106
no thanks on the 440. this isnt a project truck and i dont have a project wallet. this is just one of my toys. i have a jeep that needs alot more than my truck. just trying to finish one at a time.

Something is wrong here. Are you sure that something is not blocking the gas-pedal from going all the way to the floor? Hell, I know that my V6 would shut off. I have seen 318s shut off before.

I thought that the "4th gear" was an overdrive, not really a pulling gear but a cruising gear once you reach speed. Maybe the PCM is altering the shift points to remain in third gear. Most stock cars will do less than 105 mph in the quarter mile and the PCM specs might be geared to changing outputin a short run versus road course conditions.

Back when my '89 Shelby was stock it'd do 105mph, and that was with 175hp 318LA. It did have 3.90 gears, and that's what I was hinting at with a gear change. The 318 has all the makings for great performance (proven countless times), especially the Magnum version, but if it's meeting aerodynamic and road drag at a lower gear that keeps it from pulling any higher, shifting gears could actually slow it down as it is then moved further away from best power. Changing gears will improve accel. and may/or may not improve top speed depending on what gears are used and where in the powerband the gears move things at higher speeds.

zoochboy 4th gear is overdrive. but that dosent mean you cant accelorate while your in it.
idk about the shift points but i shift it manually when im racing so that has nothing to do with it.
gen1dak i totally agree with the gear swap causing less top end. but 355 to 410 would prlly increase.

I think, as long as the gear swap isn't too steep, the engine will be in a better place to pull more power at, say 105, and it may pull a bit higher speed. On the Shelby, at 105mph, the engine was over 4,000rpm...much closer to hp peak. They claimed it'd do more like 113, and maybe it could've managed 108, but ol' flatnose used the streamlined brick principle of aerodynamics, and 175hp just wouldn't do better. Anyway, it will at least let it pull higher in 3rd. Still, and by far, the greatest benefit will be the better accel.
