What's the superior engine?

 

Same engine .. the LS6 is really just a mild H/C LS1 ... M

 

I didn't say anything about the LS1.

 

The LS2 will have more cubic inches and a better intake system utilizing the 90mm throttle body, along with LS-6 production heads. Stock for stock, the LS2 will be superior, but once one adds things like the 90mm FAST intake, more cubes, and other minor mods to the LS-6, I don't think the LS2 will be all that superior.

 

it has more cubes and a higher CR.


itll most likely respond better to boltons and internals modifications.



they both dyno similarly.

 

Well, of course, I know it's 366 cubes to 346. I was wondering mainly about internals though.

 

Just because they have near the same hp rating doesn't mean they dyno the same. The dyno curves mean a lot more than peak hp.

 

Very true man, well said...

the graphs ive seen of both they make similar power.



their curves are most likely similar too.

 

I was thinking that their dyno graphs were very close too.

TONY

 

There is a graph that compare the LS6 to LS2. The LS2 showed better area under the curve until 6K RPM where the LS6 pull 5 more HP. I would take the LS2 motor over a LS6 any day.

 

lol I can't wait to see what new problems pop up with this 1st gen LS-2 engine.

 

Bad optispark, piston slapping, wonder what's next...

 

I know the '01 ls-6 engine had quite a few problems with bad rings, and a few bearing issues... LOL

 

From what I have heard, the LS2 has more on the low end than the LS6, and even though peak hp is basically the same, the C6 should be able to post better times than the C5 Z06. More cubes and more playing around with the valvetrain and heads is what did it, I guess.

I'll wait to sell my soul for the C6 Z06, though.
