Which LS3 are we talking about? For the Corvette? For the Camaro? For the Pontiac GXP?
LS3 that's in the Corvette... > 6.1 Hemi .... Simply due to the fact that it makes more rated HP, and is more fuel efficient... (which I know you said not to talk about) but I just had to throw that out there. I'm also willing to be it weighs less.... Don't quote me... Or we just talking about the LS3 in general?

I think this is kind of a moot point, since Chrysler basically photocopied the LS3 block and put different heads on it.

lighter more efficient probaly easier to increase the power with aftermarket... the better question is how is the 6.1 still being compared to the LS3? |

Chrysler likes to keep thier code stuff to themselves.. Chevrolet lets anyone and everyone have the code..

I thought I read that the HEMI's cylinder walls are not as strong as LS-engines. I know the first LS1s were pretty thin and later ones would accept a little larger honing, but I thought I remembered seeing that the 6.1s were thin. I think a lot of what's been posted is obvious regarding power and such so I won't beat a dead horse there. It's aluminum instead of heavier iron. I'm not sure of all the options for the HEMI, but you can get to 427 c.i. on an LS3 without resleeving (I've only seen sleeving options to get 426 on the HEMI, but again, I'm sure there are other options.) I believe the HEMI is more complex, at least in the ignition department. It's my understanding HEMIs needed double spark plugs in the past in order to burn off more the unburnt fuel in order to get past emissions; again, I don't know how reliable this is. LS-engines don't require this.As a MOPAR guy I'm sure you could give me insite there too I know that LS-engines have pretty good rods and cranks but the early rod bolts were a liability. I've read about many LSXs (not the block, just generic for LS1, 2, 6, etc.) running 800 RWHP with stock cranks and a lot running with 600 RWHP with stock crank and rods and the LS3 has, largely, components from earlier LSX engines.
I think it's hard to argue, from the standpoint of what past posts already have, that the LS3 is just plain superior from the factory. When you start modding it, that might change, but I don't know enough about the HEMI to argue that...

Hey Muscle Master! You should have driven over to Indy this weekend to meet us all. I really want to checkout your Charger in person.

Cool - thanks for the link. I'll be doing more homework. I know you Dodge boys aren't going to stop with your 6.1s
