The new for 2008 LS3 appears to be very similar to the LS7 and even uses some of the same components. Does it also use the same 6 bolt forged alloy steel bearing caps that are used in the LS7? These caps are mentioned in all info about the LS7, but nothing is said about the caps used on the LS3. Also, does anyone know what kind of production numbers the LS3 will be seeing per year?
LS3 vs LS7

Well, the LS3 isn't quite as close to the LS7 as it seems you think. It doesn't have sodium-filled valves, titanium rods, isn't hand assembled, doesn't have the larger exhaust manifold, ect.
And assuming GM sets production at the same levels as the LS2, probably 40k a year plus other possible applications(Trailblazer SS) but all in all about 40,000 annually.

I also noticed a few weeks ago that the LS3 and LS7 have almost identical hp/liter figures:
LS3 (with NPP):
436 hp / 6.2 liters = 70.32 hp/liter
LS7:
505 hp / 7.0 liters = 72.14 hp/liter
Only a diffrence of 1.82 hp/liter; if the LS3 had just 11 hp more, it would be at the same 72.14 figure as the LS7.
I love both. What a great time to be a Corvette enthusiast!
