I'm not sure of the precise cc's but the LS2 is generally referred to as a 6.0 liter engine which would translate to 366.1425 cubic inches. The following link leads to more detailed information on the LS2 engine:

In GM's literature when the 2005s came out, they said it was 364 cubic inches (5970 cc). 6.0 liters is only an approximation.

The LS3s are 376 cu. in.

Actually it's a 428 but GM Advertizing preferred to use the 427 number since the 428 was associated with Ford. Instead of the usual rounding up to 428 GM decided to round down to 427.

LS1 = 346 Cu In
LS2 = 364 Cu In
LS3 = 376 Cu In
LS6 = 346 Cu In
LS7 = 428 Cu In.

Although not a Vette engine you can add to your LSX list the LS4. It's a 5.3 L some like to call it a 327. I have it in my Monte Carlo SS.

Nice list thanks for sharing
