interesting comment on jalop:
7.0:1 would be WAY low
OF NOTE:
GM's number on this engine: P5T4373AP.
How to read these pre-production codes?
This engine was made in Pontiac (GM Powertrain HQ) and it is a 2015 LT4. It is, however, missing it's build level designation, but being 2015 I'm guessing its pretty close to final.
Also, I really wish people would stop using the "Z07" thing. The Z06 has been around since 1959. Z07 was a higher level version of the Z06 on the C6, and I'd expect Z06 to continue on in C7. I also doubt there will be a ZR1 version of the C7 (there wasn't a ZR1 C5, but there was in C4.... Hmmmm....)

Agreed, I wasn't talking about the w 7.0m thing. I was just wondering what kinda compression GM is shooting for with their first (as far as I know) boosted DI V8. Kinda think that where these engines will shine IMO anyways. I'd crank up the compression quite a bit.

I'd bet that there is at least one Silverado running around Detroit with this engine in it, which would explain the transmission. The truck is already set up for a Gen V engine, there would be plenty of room under the hood for easy access/instrumentation, and nobody would look twice at it on the road.
I am too lazy/ill-informed to do it myself, but somebody could pretty easily take a look at this photo, count the pixels to determine the pulley diameter (compare it to the throttle body, an object of known size), and back into how much boost they're running based on what the LS9/LSA figures are...
