The engine I seen had adjustable cam timing and 4.065 boreX3.622 cast crank with square port heads. It appears/rumoured to be going in the Escalade first.
Sounds like they may need to update that release.

Recent leaks from Holden in Oz is that this same engine in 6L form is due to make an appearance in all standard V8 models from Jan 1st due to new emissions laws. So maybe GM Oz will be the first.

It looks to me like if you only bore it .005 to make 4.07 bore (which is reasonable and leaves room for future rebuilds) with a 4.1" crank that should make it 426.7 CI, basically a 427 without the need for overpriced/unreliable sleeves. Stuff it with budget rods and pistons @ 11.5:1, top it off with some LS7 heads/intake and a good size cam, spin it to about 7k and I'm thinking 550+rwhp with great tq curve for about the same price as current 402 setups!
So here is the possible breakdown for a L92 427 CI stroker beast...
L92 block: Approx. $1100ish (if close to LS2 block cost)
Eagle 4.1" crank: $925
Scat rods: $440
Mahle pistons: $580
Rings: $170
Bearings: $150
LS7 heads/Intake from SDPC: $2000 + maybe $800 for valves/assembly?
Cam: $350
Timing covers and timing set etc: $175
Machine shop costs to assemble, balance etc. $1000
Total: $7690!!!
I'm sure I've forgotten something and the total price is probably a little optimistic but you can hardly get a LS1 427 shortblock built for much less then that right now!
Feel free to address any mis-pricing. I was just sitting here brain-storming and pulling #'s off the top of my head.

I was just wondering, does anyone know if the LS1/2/6 style heads will fit on the L92 block?
Therefore being able to make use of some ET heads/Fast intake setup instead of having to worry about the LS7 type heads and intake and making a TB work...

The LS7 block will accept the same valley cover timing cover and oil pan so why bother with the LS3 if this one was released first. Seems to me that the LS7 block is what everyone would want.

Would it be worthwile to wait for this block to come out or stick with the iron block? My current project is having LME build me a solid roller 408 with ET C5R heads and a Beck sheetmetal intake that would need to hold up to a 400 shot. Would this aluminum block withstand the abuse?

Note/Question on valves:
Just because GM used Ti valves on the LS7, doesn't mean they are required. The Boss 302 (I had one in 1971) had 2.21" intakes in '69 and 2.19 in '70. Steel. BBC engines have valves that size and larger...steel.
Wouldn't stainless steel valves work fine? Maybe the Ferrera hollow core?
Next note/question:
Why not cut down the rod jounals to 2.0 or smaller, especially with a 4340 crank? Custom rods for the small journals would be a lot lighter.
