Where can i get 3.55 gears for my L99?
After calculate and consider my desire ratio is 3.55.
But where can i get them? I read that the 3.55 diff from the V6 doesn't fit to swap the hole diffhouse. Is it right? Then does the Ring & Pinion set for the V6 also doesn't fit, right? Aftermarket i don't find an Ring & Pinion set for the V8 Why 3.55? In the 5th gear the car should be run 169 mph at redline with 6.000 rpm. With 3.7 i lose to much speed. The 3.45 from the LS3 seems to me to be little impact at the acceleration, isn't it?

You're right, the 3.55's will not fit in an SS diff.

From what I've seen, the 3.45 gears are ideal for a DD, especially if you decide on forced induction. 3.73s are great for the manual SS because of the high first gear (3.xx, right?). But for my car or an automatic V6 or L99, you probably don't want more than 3.45.

Do you mean a 3.45 is really noticeable? That's only 5% difference and brings arithmetical only round 22 ft. lbs.

3.73 is great for the L99. 3.91 and higher are great for the LS3.
