392 Hemi > 5.0
Only by a slight margin though. Out here the 392's are running mid 12's stock all day and getting dangerously close to the 11's with just a tire. With the newfound power they run very well.

I'm saying a tune is necessary. The stock shifting is too lazy. Your car is entirely different, lighter (and lighter with mods), stall (did I read that correctly?), and the power delivery is different. And isn't 424 a little low for a cam and headers? Maybe you make more power than that dyno reads? By the way, have you dyno'd with and without the cutouts? What about throughout the rpm range?
I know for fact that my car will make more than 424 on pretty much any other dyno...thats irrelevent. **** dyno numbers, they dont mean ****. Its apples to apples. Me and the 392 used the same dyno, and made similiar power, and should run SIMILIAR times minus the stall advantage. Which may be .2/.3 tenths. Who knows tho, im almost certain that its makes more torque way down low than i do so that may just make up some of the advantage my stall has.
The best gain ive seen with the cutouts open is 10 rwhp/tq.
FYI Ive see 6 speed 6.1's put down 320rwhp and L99 Camaros put down 299rwhp on the dyno i use.

The power is great indeed. The added weight isn't.

It is a low 12 car idiot, theres a ******* video 10 posts up. Its a thread about a 392 which you know nothing about. You cant go 2 posts without mentioning your 5.0, i at least keep my mopar faggotry to posts about mopars. Jesus christ.

I wouldnt say my car is lighter than a 392 chally. It may not be a lot heavier if at all but i def will not say its lighter...The only mod that u metioned that gives me an advantage is the stall...I will say with just tires they wont cut a 1.5 sixty foot but with only 8 less rwhp and probably a much better torque curve I dont see why it couldnt run at least sum 80's-90's with good air.
You car, with the different exhaust, plus the added weight and refinements of the 392, probably weighs a minimum 100lbs less, if not more. The stall and the shifting are big, big factors in slowing down the 392.

12.3s/12.4s

I could be wrong, but I doubt it. And good air isn't going to help the ET any better than the guy that ran a 12.3 with a 1.8x 60ft. It will help the mph.

Weight, stall, if you're using smaller diameter wheels (DRs/slicks) and tune all make a big difference. .2 on the tune, minimum, if not more.

Ill still beg to differ on the weight...
Stall might slow it down outta the hole but that great low end tq is making up for it sum i bet.
I run 28" hoosier slicks (stock height=stock gearing) and ask anyone that knows ne thing about drag racing. A slick will actually run a slower time than a comparable DR, thats if the DR hooks.

That car had tire change. There fore it is not stock. But in your small world that is stock. So then the 5.0 is a low 12 car also. here the ******* video you stupid ****. My car and us getting loud to **** the SRT8 Chally and SS off that was running high 12s and low 13s all night. You Mopor bitchs are worse then F body owners. Don't be mad Ford is doing better with smaller engines and less power.

Ya that it... Don't worry we all was shocked to hell. The 12.1 rub was first then the 12.4. Later car was back up same night with another 12.1 and 12.2 runs. DA was about 500. TX October..
Any one know what the fastest a SS went with tires only. I know fastest "bone stock" is listed as 12.5.
As mentioned the new SRT8 is fast. But saying it is a solid 12.1-12.3 (low 12s) is hard. Yes all things perfect driver, track prep, great air, on drag radials sure. Solid mid 12s I would go with 12.4-12.6.
I would say that for a perfect driver etc 5.0 as well. Or Even a SS. Well I don't know about low 12s for a SS..LOL

I promise you good air will drop et...I see as much as .3 drop in good air.

Stall might slow it down outta the hole but that great low end tq is making up for it sum i bet.

But anyway..
I agree on good air. I have dropped .3-.4 going from 3500 DA to 200 DA. TX sucks during the summer.
