Thanks for the info.

The Cadillac blower engine makes over 106 hp/L and 97.5 lb-ft/L. I don't think GM would let the LS9 out wilth less specific output. That equates to slghtly over 600 lb-ft and 660 hp. We'll see.

Underpromise, overdeliver.

GM told me that this will have 620/600 at a MINIMUM.. the LSA caddy stuff is on embargo until the middle of January but the output was less than the 'Vette.

I agree. Regardless of what they rate it at, they are choking it down.

I have heard that it can make 700 FWHP without breaking a sweat...

I've heard the same.. they had to de-tune it.. also heard that it has almost ZERO heat soak..

I think we talk to the same people....

Every performance figure I see above is lower than what I have heard is true.

Well, it's been tradition for GM to under-rate thier hp/tq numbers... in any event, it's one bad *** engine

cant wait to see what a nice blower grind cam, headers, smaller pulley, and ported heads will do sounds badass!! i wonder if the new clutch will be transferable to other models like the current Z06...a GM twin plate clutch would be pretty sweet and probably come in less then a textralia or one of the other twin plates out there

The ZR1 will have a new twin disc clutch and will run the new TR6060 six-speed trans (Tremec)

the best part is that we will be able to swap the top end stuff right into the ls2 trailblazers. being as its going to be based on a ls3 bore demension, the valves will most likely clear with ease. i think im gonna have to start a ls junk yard and get a peice of the action lol

The pressures generated by the blower and combustion displace the cylinder head by up to 16 microns.

When will all these parts be AVAILABLE!!!!
I'm interested to see if they sell it as a crate engine and what it will cost?
If you do a quick ratio of LS7 crate engine cost to Z06 MSRP cost it is about 18.65%
Thus if MSRP of the ZR1 is $100k it should be in the ball park of $19,000.
If that is even close to accurate I WILL be buying one for my 95 TA!

My guess on that crate engine is 19-20k, so start saving up
