LS7 a 7.0L Looks like the Caddy team forgot to use some duct tape. I was at the World Challenge race at Laguna Seca over the weekend, and I got to see the Pratt & Miller boys change an engine in one of the CTS-vR's. Look what was cast into the block:
Here's a pic of the top of the motor:
Look at the big runners and the 90mm TB. This is the same setup that was on the GTO show car.
This is the head casting number:
You can also see the big exhaust port. You can't see in this pic, but its a D-port.
This is a knock sensor in the side of the block:
This is what makes me think that this must be a production Gen 4 block. The exhaust ports can also be seen.
The car:

Is that a intercooler I see under the hood with a 427R. Someones got alot of money in that setup

Louis, you aren't kidding man. It must definitely be an uphill battle when the rules are set like that for factory teams. It must be nice to have GMs budget too

In the last pic, there was a little fence right where I was standing to take the pic. When the had to take the engine out, they had to move the fence to fit the hoist in front of the car. I was literally feet away when I got those pics.
