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:

 

Looks sweet

 

Duct tape is your friend Nice spy shots there Chris

 

Nice stuff hunh

We got to compete against that thing with a Standard bore/stroke, LPE headed, GrandAm cammed 346

Thats what running against a factory team is like. Ryan can tell you

 

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

 

NA, 358 CID. 4.1xx bore, 3.2xx stroke, 2.12 intake valves and so on...

 

Nice shots but I am going to have to confiscate those and retire to my quarters...

 

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

 

What part of the block is that 7.0L cast into? I can't figure it out. I'm guessing to the side of the crank pulley area?

 

Yep. May have been the back since the motor was on a stand. It is in the same spot the std. 5.7 is on any LSx block.

 

It's right by the water pump outlet. There was also another "7.0L" on the back of the block.

 

How'd you get close enough to take those pictures? They just let people walk up to them?

 

Hmmm.. wonder if the GM guys will be happy when they surf this thread tomorrow

Is this motor public knowledge yet?

 

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.

 

that is so bad ***...



Dont antagonize the GM guys too much no brian

 

The crew members didn't seem to be too happy to see a guy with big Nikon SLR snapping close-ups of their motor.

 

Haha! Nice work, man!

 

 

Good info...

 

Looks like it is cast in the front. You can see where the lower radiator hose attaches.
