408 Stroker or Supercharged?
Well if you had to make a choice which one has more power and better ETs, the 408 stroker or the supercharger at 9-10 psi?? Now the 408 Stroker Kit that KRC Performance offers, is that the entire engine? or is it just a kit to bolt on to your 5.9 engine? 4800 dollars isn't bad at all if that is the entire engine.

Nope.
That's not the whole engine. That's the short block. You still have to spring for heads, intake manifold, throttlebody, injectors, fuel system, etc., etc. Unless you just want to just use those pieces off the stock 360 you have now (you DO have the 360, already, right?).
But, here's one way to think about it. 10 psi is kinda hard on a motor without taking special steps like O-ringing your block and using studs instead of head bolts, etc. So, basically, if you can make 400-500 horspower out of a naturally apsirated motor that may cost $6500-$7500 turn-key, then you may actually come out ahead (in the long-run) of the $3500 SC + the machine work to make the motor live under 10psi. The super charger may be cheaper, but you will always have to looking at that boost guage and that temp guage. And making sure your oil is always changed so that the SC bearings are okay, etc.... It's only my opinion, but i would go naturally aspirated. |

408 or s/c
I just finished doing my paxton S/C 408 .
The biggest advantage on the 408 is the low end torque and you adding almost 50 ci. My previous setup put down 450 rwhp/490 tq . The main reason I made switch to a 408 was for the duribility of a professionaly built bottom end . I do think that the new Paxton Novi 2000 S/C for the 99-01 Dakota is Killer and would be a reliable and duriable setup for an everyday driver that can still pass smog. That being said go to a 408 will probally end up in the NOT smog legal catagory. Hind sight is 20/20, If I had to do it all over again I would do a stout 360 bottom end and keep the S/C and do some gears. If you have a big Wallet do the 408 and I would highly Recommend "The Fastman" Dan Arcand Scott |

So, just for Sh*ts & G*ggles....
Well, you just got done with a 408 and I've seen the video of your truck on the Dakota R/T site. Nice work, there.
So, is my $7500 estimate a fairly accurate guess for building a turn-key naturally aspirated 408? If I am trying to make a dead-reliable daily driver to the tune of about 450 hp? No provisions for nitrous or force induction, just regular 20,000 mile per year motor. |

See my signature, If you want 450hp all motor then Call Jon Davis 765-348-4386 The first dyno was 425hp on a carburator, it is getting a bigger cam and being dynoed with the 4bbl throttle body. Most likely it will push that 450hp mark. Thanks

It cost me 1590$ for a 406 Stroker Biult by Kammer and Kammer Racing and Bought through Randy Pile www.worldwideperformanceparts.com.
I agree with a couple of the others hehehehe DO BOTH. I went with an 8lb Vortech and stroked it to 406 that whole deal has cost me 8500$ to do the whole truck Top to bottom. |

wHAAAAAt?????
You got a 406 motor that was built by Kammer for $1600??
Are you sleeping with Randy Pile or what? Is that just for the kit? I guess I am interested in a turn-key price for the motor. Short Block, heads, intake, TB, fuel injection, headers, and then the stock accessories off a junker 360. I want to buy a Gen II and go 12.50's for $10,000 including the price of the truck. I was hoping to buy a $3000 truck (or less) and then spend about $6000 on motor (or less) and then do soem things like lower it, give it traction, lighten it up a bit. I am baffled by the $1600 motor form kammer? Did it have a hole in the block? HeeHeeHee.... |

Yes that i s a good estimate if you are starting out with a stocker and you want all the good stuff
408 balanced with pro dampner all the good internals 3500-4000 New R/T heads ported for Big #'s 2200.00, reg port job 1700.00 Custom cam 250-300 M-1 350 Roller rockers 500.00, nice not the mopars Yea it gets out of hand quick Scott Q |

406 for $1600
Just the parts should be around 3000.00 for the good stuff and then you have to machine the block and balance....like $600-700
Hell the pro dampner is 350.00 well you get what you pay for... |

Hey, Hughes Engines has a whole slew of strokers you can get installed for 5 grand+/- "goodies". I'm looking at a 390 cid off my 5.2L(small bore cleaned-up and 4" crank). Good internals, Mopar crank radiused, modified intake and bigger TB. That's "base"; I'm thinking of adding roller rockers($250-ish) and a couple of other small mods. I'm towing an RV trailer with my Twuckie-Poo....80-odd cubic inches ought to help in Colorado!

So, I still don't get it.....
It is now sounding like you sort of put together a "run-of-the-mill" motor with no special internals and stock cast iron pieces off the original motor (stock factory heads, etc.), but then you huffed it with a Vortec at 8 psi....... Are you going to get more aggressive with boost? Will the motor last without forged steel internals?
I didn't know you put together the 408 kits that cheaply. That gives me hope, at least. Have you run a 1/4 mile yet? Have you got a list describing the rest of your set-up? Have I asked you about 100 questions? |
