55 or 63
If you road course the car then perhaps the 63 might be your preference because of the 7 forward gears. If you like to street race or take you car to the strip then I'm afraid there no contest, get the 55.
My experience with naturally aspirated motors is that they will never feel like a supercharged motor down low and the supercharged car is MUCH more fun to drive, hence I supercharged my 04 Z06, what a freaking blast, plus trapping at speeds over 127mph a real plus, not to mention the low and midrange power was simply neck breaking.

I was wondering the same and checked around. If you look at the specs for the 63 engine the torque exists at higher RPMs with 369 @ 2000 rpm and 413 @ 3000. Maximum is only 465 lb-ft at 5200 revs compared with the blown engine's 517 between 2,650-4,500 rpm.
I decided to go with the 55 because it seems best for what I do around town.
The 55 w/ the 030 package and touch of Kleeman/Renntech can only bring smile to my face and a lot others. It is nice to have the choices we have...

P.S. I also have Rentech 20's and the ride is great. Very little difference from stock.

From your signature, I see you have 55 now and jump to 63 as soon as they come out. Can you share with me what makes you do that?
Thanks in advance.

IMO my perfect combo purchase: CLS55 030 package w/ K2/3 upgrade (pulley/headers/ECU...etc...), Evotech brake upgrade, and lightweight 19's on PS2 rubber. Oh...Black w/piano black wood. I'm not asking for much... :v
