Hmmm, didn't realize the new hemi was a pentroof design, but from what I understand that is actually better. But don't most penroof designs use 4 valves? And I was only making the spark plug comment to distinguish "new' from "old" design. I realize that was for emissions.

Hemispherical combustion chambers? NO WAY. Not the new "hemi". They were great at making power (hemi heads), but very bad for clean air and mileage. The name is just a gimmick now. Dual plugs per cylinder? Even my buddy's old mid 80's 4 cylinder Ford Ranger has that. Big freaking deal. Not.

Does it really make any kind of difference what a motor is called? If DCX decides that their 5.7L and 6.1L motors are to be called "Hemi's" simply for the reason that DCX owns the rights to that name and not necessarily due to it having hemispherical combustion chambers, dosent that still make it a Hemi? I mean, what makes a Boss260 or 290 a Boss? It's a Boss cause thats what it's called, it's certainly not because it shares the same architecture of the old Boss429.
Nitpicking over the name given to a motor by a manufacturer for nostalgic or marketing purposes is mundane. It's not as if DCX were marketing a 220 HP 4.0L OHC
motor and calling it a Hemi, so I don't see the rip off here. Hemi's were performance motors - and like it or not, these motors perform well. What's an 04' Mustang Cobra put out for HP? I know it's got a blower. I know it's at least 400lbs lighter than an SRT-8 300C. Plus a 300C is about as aerodynamic as a brick wall. Real Hemi or not, these motors are both hyped to be good performers, and they are just that.

The 2 plugs are for emmisions...as stated earlier. It doesnt use a pentroof design. Its not a true HEMI either, but some semi-hemi heads. It has 2 large valves, whereas a pentroof would have 4. Cant we accept the fact that the 'hemi' just simply outperforms our fords? (in its class)

yes I can, but I still have a problem with whoever brought up the 5.7 hemi being quicker/better than the 6.8L ford. In it's own class the hemi has it hands down, neither the ford 5.4L or a GM 5.3L hold a candle to it. to be quite honest its pretty impressive, It's just not designed/ meant to/ or suppose to do better than the next class up. Actually in reality the performance is probably beter than the next class GM which would be the 6.0L gasser, although, I as many others have been quite disappointed with the 6.0L in performance vs economy of this motor. Heck the 8.1L get as good as economy as the 6.0L, and the 8.1 is worse than the V10, whats up with that??? But plain and simply the 5.7L Hemi out does the respectable engines in the half ton class, period, end of story. I don't think anyone will argue this point (I'm poditive I'm wrong about this though, lol)

Unsure of the weight of each truck, but I'm willing to bet it's close...if anyone can prove this whole assumption wrong, then I will stick my foot in my mouth.
The Ford makes more power, and torque, a LOT sooner, with a lower gear set, and being that I am assuming the weight of these two trucks are *somewhat* comparable, the V10 powered Ford will walk away from the 'hemi'.
Now, say we have the same config. dodge, but a CC Ford instead, then I am willing to agree to a 'hemi' victory...

Would seem the Ford would have at least 10% gearing advantage (given the 4.3 to 3.9) and probably more often closer to 20%+ gearing advantage (4.3 to 3.55). If torque can be multiplied then it would seem the difference in torque would be HUGE between the two.

Umm excuse me.
My mom's 2000 Silverado will walk off and leave a Hemi. Been there done that several times. Including those ugly *** little rumble bees. Not sure on engine size and she's not here for me to look, I just know it's the 300 horse engine.

The 2500 and 3500 chevys had a 300hp option in 2000 but not the 1500s.
A stock 2500 or 3500 with a 6.0 will not beat a hemi 1500.
Does your mom have a 1500?
The largest engine avalible in 2000 silverado 1500 was a 5.3 rated at 270 hp at the time and 315 ft lbs of torque. Decent specs but still will not out due a hemi in stock form.

I do like the gms but the 5.3L won't get it done in a 1/2 ton and the 6.0L is dog in the 3/4 so that wouldn't even be close. The 8.1L might give it a run for it's money but only time slips would tell.
Ace, You're absulutly right, the torque difference is huge with the different gearing, and last time I checked torque is what gets a vehicle moving, burns tires, tows loads, and makes 7000lb trucks feel nimble.

I mentioned the lower gear set. That's what a lot of people who don't believe the V10 would win in a 7000lb truck are over looking. With the 4.30 gears, I'd be confident on a win against the 'hemi' 1500 in a 3/4 ton Ford. At least close. Lets try and get some video footage from one of you '05 owners (Charlie's out, he has a tuner) against a 1500. Then post it, win or lose, that will settle everything.

KingLariat, I have been in the truck and done it, whether or not you choose to believe me is irrelevent. I'll ask her to keep the camera in the truck on the off chance she sees one going to/from work, and I'll ask my gf's neighbor if she'd be willing to race, but I honestly can tell you I have been in that truck and done it.

I dont think the 6.0 is a dog. It does have a very flat torque curve. Much better than the hemis. Ive driven both. Id say the 6.0 off the line no problem but that hemi gets fast above 4000 rpm. The 6.0 seemed pretty torquey to me. It sucks with an auto. The auto takes all the pep out of it.

Well I was on dodge.com building and pricing a Dodge SLT (bored as hell), and you cant get a Hemi with 3.92 rear end gears, only 3.55's. Cant get a 6 speed either only a 5 speed auto. I bet if you put the 3.92's in the back and a 6 speed in a hemi with a short bed reg. cab it would be quick. They are makeing some crazy deals though. They take off a grand total of around 8,000 bucks when you lease one. you can get a V6 6 speed base model 1500 for just under 14,000 not including taxes.
