LS1 and LS2

[ws6drbob]

I am a little confused guys. The 2005 C6 corvette is coming with a 400hp LS2. Is this engine a totally different engine or is the same platform as the LS1(like the LT1 and the LT4)? I went to chevy's website but couldn't find any info. Just curious if any of you guys know.

because it's keeping the LS designation, it should be of the same family as the LS1/6, like the LT1/4 are the same (Essentially the same block with nearly everything else being different).

I just found a pic of the engine bay in the C6 and it appears to be the same block as the LS1 and LS6. The only reason i had to ask was because i know that the ZR-1 corvette in the early 90's had a LT-5 which was a completely different engine than the LT-1 and LT-4 yet still carried the -LT- identification code.

I was curious about this too- i read a motor trend article on the C6 that called the LS2 a "Gen 4". Kinda looks to me like it's still LS1 based from the specs and technically would still be a gen 3

LS2 is 6.0 liter.

Yeah, it is a bored 6.0 liter. It also has 10.9:1 compression, and better exhaust and intake flow. With a 6500 RPM redline.

It's funny... that is more displacement and more compression, with the same redline as the LS6, yet it is rated at 5 less horsepower... can you say underrated?????
