my question is which is the better engine (better engineered / more technology) the 6.1 litre hemi or the 6.0 litre ls2? just a fraction larger the hemi makes 25 more horsepower and 20 more pounds of torque. shouldn't the base corvette have a more powerful engine than a dodge sedan? will chevy step up with the base vette? is there room for a factory horsepower increase with the ls2? just food for thought.

Weight of the car, suspenstion, tranny, etc...... its all a factor.

Look at the SLK 55 AMG 355 HP engine and a 0-60 in 4.3secs. That 7 speed auto kicks ***

by the way I burned one of those dodge magnums with the hemi at a stop light. That car is way heavy for that Hemi - even with that 400ish horses it is putting out.

My wife has a Magnum RT (wagon) HEMI 5.7 The horse power is 340 and it has 390 ft lbs or torque. It also weights in at 4000 + lbs. and time form 0-60 is around 6.4 seconds.

The new SRT8 HEMI Magnum has the 425 hp 6.1 liter with 420 ft lbs of torque. 0-60 mph time in the low 5-second range and capable of covering a quarter-mile in the high 13-second range.

I have not seen any SRT8's yet on the street or showroom yet, but in either case, the C6 has em both covered for track time.

I fully agree that the corvette is better, but I think the question here is he is saying for .1 of displacement they are pulling 25 more hp than the c6 is at the crank which I can fully appreciate.

Both engines have very good technology behind them. I would like to see the weight difference between the 2, I imagine that the corvette engine weight is a lot lighter.

On the Hemi Forum, the Hemi is better.

On the C6 Forum, the LS2 is better.

Duh

c6harley, thanks for the help. two impressive engines. i still consider the vette a muscle car as well as a sports car. that being said, if my neighbor asks me how much hp my vette has and after answering him, he responds, "oh, my 300c with a 6.1 hemi has 425 horsepower." "i would have thought a $50,000 tuned 6.0 litre vette would've had more hp than my $40,000 sedan. what do you say next? no doubt the vette will win a stoplight to stoplight contest. but what about horsepower bragging rights? --- again i started this thread to discuss the two engines, technology & limitations. thanks, timmyb

Is it just me or does it seem that most of the new Dodge's seem like pigs? They have to have all that horsepower because they weigh more than an Abrams tank!

The new hemi is a nice engine design, and the factory hotrodded it pretty hard, but it is heavy, and in a heavy car. The LS2 is a much lighter engine, in a lighter car, and hp to weight is what wins races.

The LS2 has a pretty mild cam and a fairly restrictive intake manifold. A cam and intake swap would put it up over the hemi, but since Chevy has the 500 hp LS7, I doubt that they'll tweak out the LS2 to push it to 425-450 hp. It would be easier, and make a much better mannered street package, to just *detune* the LS7 down to the 425-450 hp range.

They wouldn't need the dry sump or the titanium valves to hit 425-450 hp, and so the cost would be nearly the same as the current LS2. Best of all, the mild state of tune would make for more reliability and fewer customer complaints. Nothing beats cubic inches for making streetable power.

Also consider the MPG you get with the LS2 versus the MPG you will not get with the Hemi. Why does 0.1 lters and 25 HP cost so much more fuel per MPG?

WhiteDiamond

It really doesn't matter because DC has gained market share since the release of the Magnum/300 series and GM has lost market share. The 6.1L Hemi is a very nice engine and it puts a American 4 door sedan, 300C SRT-8, (the Magnum SRT version is not out yet) in the territory of AMGs in terms of performance and about 50% of the cost.

I am still waiting to see the SRT-8 version of the Magnum, as I have considered adding one to the family. The Vette is an entirely different vehicle and should be viewed as such. If DC decides to put the 6.1L Hemi in a chassis that competes with the Vette, then this discussion would mean something.

A diesel locomotvie probably has 20,000 horsepower. Would you want to park that in your garage so that you can have bragging rights on horsepower?

Corvette400400

Also the SSMEs on the space shuttle pruduce a tad over 37,000,000 horsepower, now who wants to start a pissing contest with that? Bragging rights are only good when the whole package is considered, its not all about horsepower and torque, gotta have the right weight, drivetrain, transmission the whole deal, the dodge engine is good, but the package they put it in doesn't let them brag and win in our territory, for a powerful sedan, awesome but for a world class sportscar like the Vette, not even in the same league of bragging capability. Just IMHO.

Big Lebowski

C'mon...are we really comparing a station wagon to a corvette?

Just because Dodge dropped in a big engine and threw on some chrome wheels does not even start to put the magnum in the same league.

How is it American? Chrysler is owned by a German company. Do you consider the Toyotas that are made in the US as American?

Jeep SRT8 0-60 in under 5 and 13.5 in the 1/4 stock!!

WOW!

No way. It probably weighs more than an Abrams tank.

Check out this info I pulled up from: http://www.allpar.com/mopar/new-mopar-hemi.html
“However, the proportion of regulated pollutants is a problem for Chrysler. Bob Sheaves noted:
The Hemi design combustion chamber is one of the poorest designs for emissions - why do you think it took so long to get it into production? It almost did NOT make emissions test requirements even with the modifications. ... Today's Hemi is that (a "Hemi") in name only. [Editor's note: Bob is referring to the head design. It is not a true hemispherical head, but looks vaguely like a hemispherical head with parts filled in.]”
Seems the new Hemi isn’t really a Hemi after all. It’s misleading marketing strategy. There’s a word for doing that. Let’s see . . . . . what is it again . . . . oh yeah . . . RICE!
Also shows the dressed engine weight is about 485 lbs.
Scissors indicated in one of his 6-04 threads the weight of the LS2 was around 322 lbs. Don’t know if that’s dressed or not. Anybody got the specs on it?
Another interesting comparison is the C6’s 25/18-MPG rating and a curb weight less than 3200 lbs. verses the 300C SRT-8 at 19/14 and a curb weight of 4160 lbs.
Timmyb, you can go back to your neighbor and tell not only does your Vette have him beat with weight verses horsepower ratio, but also he really doesn’t have a Hemi. It’s a rice job straight from the factory!

Well, actually I do. Toyotas are designed in California, made in Georgetown Kentucky, and sold all over the US.

As to Chrysler, they're the richer half of the merger of Mercedes Benz (made in Alabama) and Chrysler/Dodge/Jeep.

I think almost everyone here is missing the point of this post. Read the title again:

Dodge 6.1 HEMI vs. Chevy LS2 6.0

He's asking about the ENGINES, not the cars. It would be interesting to know how good the new HEMI really is, and how it compares to the LS2. They are similar in design and output.

Another way to look at this (with a level playing field): Would the Vette have better performance with the HEMI or LS2?

z06z06z06z06

g35c6mt, thanks... would the vette be a lttle quicker with the hemi, it's got more horsepower and more torque. although its not a space ship or a diesel. production costs might be pretty close although gm is now throwing our corvette ls2 engine in every other vehicle coming down the line in about the same state of tune (ex. gto, ssr, trailblazer). back to my original question (would be nice if one of our engineers chimed in), which is the more technologically advanced engine. furthermore if it is the hemi, cheers to daimler chrysler for putting it into an affordable sedan. however, i don't believe a less expensive domestic sedan should have a larger displacement, better horsepower & torque ratio than our base vette (6.1l 425/420 to 6.0l 400/400), do you? as a sidenote chevy does appeared to have stepped up with the ls7.

Forget the hemi.You should worry about the new cobra with 450hp plus
