i hear the KB is real hard to tune. go to blakdakrt.com and look up the thread "is kennybell any good?" and make your decision
the only guy that i have heard of that is running a KB on a 5.9 dakota is surfa. he has video of the truck on that webside also.
there is a guy on dodgetrucks.org who is installing a KB on his ram right now and is having problems.
if you have the 4k to spend on a KB, why not get a vortech?

If you're going to spend $4,000, stroke the motor. I tried the blower and I tried a stroker motor. Hands down, the stroker is better. It's easier to tune, more reliable, less noisy, etc.

I've thought about a stroker, it looks very attractive, BUT, how much would it cost to have it done? I can't pull an engine and machine it, I'd have to pay for that, also, emissions, how will it hold up? This is also my daily driver, that is why I am considering the SC, as long as I keep my foot out of it, it won't poor gas in the engine like a waterfall, something tells me that a stroker is going to eat it no matter what. What all is involved in stroking the engine, and where would I have it done??

Just looked on Speedtweaks and they have stroker kits you can buy...the basic 406 stroker runs about $1995 then they have 2 408 stroker kits one is $2270 and the other is $2585. Alot less than a blower...alot of money left over for the installation. The blower is 4 G's w/o installation. Either way your engine is still gonna guzzle the gas.

OUCH
labor for a stroker is going to be about 4 grand, that includes some parts that don't come with the kits, but are needed, and computer work, so a 408 stroker done by someone other than me is going to be about 6200 +, a kenne bell is going to be about 4800, big difference there, I want power, but I want to eat too. Since this is a daily driver, I'm thinking root charger, for multiple reasons, a stroker is more down time on my vehicle, it will eat more gas then a sc on regular daily driving, the sc is power when needed, the stroker is all time power. I can afford a root charger plus install, but not a stroker, the engine is brand new, I don't want to tear into it, maybe after it hits 100K.
I think it will be Kenne bell root charger, I'm up for a nice pay raise and a bonus, while the truck is gone for a couple of days, I'll have too cook up a story for the female :-)
Thanks Mike!

Viper, how much boost do you think you'll end up putting on it? And are you going to add an intercooler? I heard the intercooler robs some HP...I don't know if you really need one for daily driving, although the Lightnings come stock w/ one.

6lbs, as far as an intercooler, initially, no, for cost reasons, but eventually, yes, especially since this is TX. Intercoolers can boost a large amount of HP when coupled with a screw super charger, the problem is, the sc heats up the air quite a bit, making less dense air, robbing horse power, even the mod shops tell me that a supercharger is only going to perform at optimum levels when it is used with an intercooler. That is part of the reason I was going to go with powerdyne, it doesn't heat up the throttle body like the root, so heat isn't as much of an issue. I've thought about starting with a water to air intercooler first, then a sc later on. If your running 6lbs of boost, but the air is super heated, your not going to gain too much HP, the air is not very dense, put an intercooler with 6lbs of boost, you get dense air at 6lbs, much more power.
I'm no expert, just research, and applying physics laws.

why not use the vortech? they have a intercooler available, and the install is easier

Plus hasn't the centerfrugal SC been around longer than the twin screw? I think the Vortech is a little less than the Bell.

Vortech is a centerfugual supercharger, they only produce 6 lbs of boost if you are running high rpm on the engine, some root chargers will push 4 lbs at 1200 rpm. The fear of head gaskets has crossed me mind, from what I have found, the ealier R/T's were more prone to blowing them, if I were to blow a gasket, I'd take her down to 5 lbs.

well if a kb is making 4lbs at 1200 that means you will be burning more gas.
if you run a centerifical sc, all you have to do is punch it and the trans will kick down a gear and you will be in boost. that will also let you engine last longer because you can drive around out of the boost, and prolong the abuse on the engine

Its only under boost at 1200 RPM if you have your foot in it, and boost doesn't kill the engine, RPM does..
The only thing that scares me is detonation in the TX hellish heat.

I just see all these cars and trucks running SC's stock, and think, why can't a 8 to 1 run an SC on 6lbs? 6 isn't that much, I can't imaging blowing a gasket on 6lbs with 8 to 1. There are a ton of cars out there running trubo's higher than 6lbs with no detonation or gasket problems...
If a furd can put SC's on all of their's, why can't the ol 360 pull it off with no problems? I've owned a ford, so I know about "ford quality" first hand, I can't imagine that junk standing up to mods..

isnt the comp ratio 8.5 to 1?
also the head bolts are not in the ideal location for boost, and the bolt and gaskets were not made with the intention of running boost.
just replace the gasket with felpro's (there is another company that makes better gaskets but i forgot the name) and upgrade the head bolts to mopar's and you will be fine with 6#'s

Thanks for the input, I'll be sure to take that in mind, if that will fix the gasket problem, then detonation is the last thing to conquor.
It may be 8.5 to 1, I knew it was 8.something to 1.

ATI-procharger are supposed to have good kits, and also include intercoolers. Screw type sc's like the kenne belle will not seen a big change with low boost and an intercooler. The centrifigul on the other hand spin much faster( therefore creating more heat ) and should have a intercooler to give better and more reliable performance. Vortech offers intercooler and boost upgrades. The KB unit will be more docile on the street, but I can think of many more mods with better cost-to-horsepower ratios.

you can do that, but i hear the powerdyne dosent really have a ping problem with the 6# pulley. if you DO have a ping, you can also go with the 24# injectors

I got a powerdyne. I can tell you all you wanna know. I also live in texas. Install... bam easy as pie, runs cool, simple--- which means easier to work on engine. Change plugs, wires, bigger filter, msd btm, and you should be fine. Runs like a bat outta hell when everything is workin right, just dont learn the hard way... it aint fun, I've beem down that road. Also, i recommend a centrifical opposed to twin screw is one big reason. R/T's already make hella torque, so you need more hp, or your gonna be sitting at the starting line roastin your tires. Its a perfect balance this way. my 2 cents.

I have a Vortech T-trim on a 318 with 11 psi. I had the fel pro 1008's and blew the head gaskets. I now have Mr. Gasket solicor head gaskets that are made for superchargers and high compression engines. I have ARP head bolts with the moly lube and tq. them to 115 lbs. And have had no trouble with them ever since. My advice to you is if your going to put a blower on, upgrade your head bolts and head gaskets before you bolt on a supercharger. The Mr. Gasket Solicor gaskets are the best I could find. I wouldn't use the fel pro. I see allot of guys using them and blowing them when the go over 9 psi. If you like you can e-mail me viper6 if you want some more info.
