i don't think so.

the 6.4 screams all the way to redline, even in 4th gear.

from 100-150, the 6.4 gets there so much faster it's not even fair.

low end is brutal as well - 6.4 makes massive torque under 3500rpms, whereas the 6.1 doesn't make as much.

...and you feel this moreso during daily driving...

EricG: wow then your 6.1 was way different than mine. Night and day from my 6.1 to my 6.4. Pretty significant difference I thought all the way thru the torque curve.

Litos...your answer is along the lines of what I expected to hear...Torque rules on the street. If you hop into one of those small engine high boost imports that lay down 500 HP....it just won't FEEL as fast till you wind it up.

-And no...I'm definately NOT comparing a 6.1 to an import..lol I'm using extremes here...

Have you ever owned a 6.1 Hemi? Granted, mine was fast, I never lost to another one, but I always just told myself it was the driver

Makes you wonder if he owned a 6.1...

There are many reports of R/T's out running SRT's prior to MY2011. I raced a bunch of 2008-2010 SRT's with my 2009 R/T Classic 6speed with a few boltons (CAI, Catback, headers and tune). I never lost to a 6.1L. My old R/T wouldnt come close to running wiith my 392. I ran 12.9 with boltons and DR's with the RT. I then added 100 shot of nitrous (never raced a 6.1L with Nitrous) and ran a best of 12.3. Putting it into perspective, my 392 ran a best stock of 12.33, then added CAI, Zoomers catback, 3000 stall converter and drag radials and it went 11,87.

Well my 6.1 went 12.9@109 stock and 12.5@112 with a tune(Corsa and AFE intake, hi-flo cats too), that was without drag radials and the stock converter. I raced it with the baby seat in it too I trapped 114.1 once and hit 113 several times.

I mostly ran it around Cincy, but went up to Muncie a couple times and also over to Indy twice. I never had a close race with a 5.7 anything.

These VCT motors are so great on the first 1/8 mile, and I know the Eagle 5.7s can put up some good e.t.s, but they don't trap speed very well. 392 is better there, but I mostly see people just over 110, that's what my 300 did all the time. Again, maybe it was just my car, but my racing buddy with a '07 Charger could basically run the same times and trap speeds. The 6.1 is a hammer you need to know how to swing I guess. All I will say is be careful of running one from a roll, you may be surprised.

The 392 suffers in the upper RPM band and from what I've seen, it's the initial change over from long to short runner valves in the intake manifold. None the less, a CAI seems to keep the HP and torque curves from dipping at the 4800 rpm point and both 6.1 and 6.4s perform very well. No doubt, with both engines, the 6.1 from 4800-6300 rpm and 6.4 from 3500-6000 is their bread and butter range.

Also, as a side note, the 392 was performing exceptionally well last night at 85mph, legally, on Toll Road 130 in Texas

of course i did - i just don't randomly toss out statements like that without seeing or doing it on my own.

i've owned the 5.7, 6.1 and 6.4.

my SRT8300C was quick, but would get drug by it's own ball sack by a 392 up over 100mph.

i did a quick pull from 80-159mph in my old 6.1 after it had just got done being CMR'd by Brian@SNL - it was nice, but not even close to the stupidness described as the "392 top end".

it's not even close - and whoever thinks it is, must be high on angel dust.

p.s.
there is a much closer gap between the 5.7 and 6.1 than the 6.1 to 6.4.........6.1 to 6.4 is not even close.....
