LS6 (04, 05) vs. LS2 (06, 07)

Hi

I've been saving up for about a year now for a CTS-V. I intend to buy used, rather than new (just because it's more affordable).

Biggest dilemna though, is what's the better deal? Both the LS2 and LS6 have the same horsepower ratings, but i've heard the LS2 had a nicer torque curve compared to the LS6 which has its power mainly in the high RPM range.

Discuss... is it really that big a difference (noticeably) with the LS2?

I can't speak for the V but I test drove a 06 LS2 Corvette and it felt like it had 0 power in comparison to the 05 LS6 V I owned. The difference could very well have been the differential and the fact that the Corvette was an automatic though.

I always liked the old saying "there is no replacement for displacement" though so I would probably opt for the LS2 vs. the LS6. You can always upgrade the LS2 heads with the LS6's light weight valves if you want to rev it a little higher.

i don't think it's really a big difference. any of the two would serve you right.
