My father was telling me about this new Corvette he saw down at a store, and he said something that I just couldn't believe. So, I am here to see who is right. I am pretty sure he is talking about the new Vette. He said that when he walked by it that it had an emblem that said S6 305, and swears by it. I told him I had never heard of any S6 Vettes and that it probrably said C6 Z06. Now, Im not much of a Vette enthusiast, but I am pretty sure they wouldn't have put a 305 in the new ones. I looked it up and found out that the new ones come with LS3's and LS7's. I found out that the LS7 is a 427, but I couldn't find the c.i. of the LS3. Could anyone tell me what the c.i. is of the LS3 so I can put this arguement to a rest?

Well, I know for sure, there was never a factory Corvette with 305. LS7 is actually 426 CID, but Chevy added the "427" moniker to attract people to the old-time L-88s. Funny part, LS7 has a bore of 4 1/8" and a stroke of 4". That's the same as the old 428 Pontiac and VERY close to the old Ford 428.

I believe LS3 is the 5.4 lr. version. One local is very proud of his new Monte with that engine. He keeps telling people it's a 327... It's a 323, but it bears ZERO resemblance to the old small block. The 400 HP LS2 is also available for certain years, and LS1 was the first in '97.

FWIW

Well I am just talking about the newest Vette. I believe the new LS7 is a 7.0L and the new LS3 is a 6.2L.

305 rubber on the back corners.

the standard c6 vettes come with a 6.0L engine...so would be somewhere around a 362 CI...roughly speaking.
