Gump, you seem to have an inside connection; maybe you could suggest to GM Perf that using an aftermarket 12 bolt instead would return some brand credibility to the concept. I think that the extra hassle when swapping gears compared to a 9" is worth it in order to keep the car an all GM design.

While I'm not a fan of the "ringer" versions of late model Mustangs, Challengers and Camaros in Stock, I am pleased to see the manufacturers taking an interest in battling each other on the dragstrips again, and with that in mind it's great to see Chevy willing to finally get in the fray.

Looking for the real scoop on the new COPO Camaro? GM High Tech Performance gained exclusive inside access to the top secret testing conducted yesterday and we've got loads of behind the scenes coverage coming soon!

Today, we can tell you with certainty that the proof of concept COPO Camaro is an easy 9-second contender and clicked off a 9.90@138 on its maiden voyage down the dragstrip. That's right, a 9.90 on the very first pass! After that, we watched as the COPO Development team, which consists of Russ O'Blenes, Robin Wright, Scott Roslund, and Cliff Cohen, make a series of changes, taking the COPO from a 9.90 to a string of 9.70s. With slow 60-foot times (1.40-second range) the COPO has more in it but managed a 9.69-second pass at 140-mph on its best run. As you would expect from the editors of GM High Tech Performance and Camaro Now, we've got a lot more information to come... but you are going to have to wait for a future issue of the magazine to find out more!!

It may be pretty fast, but it sure isn`t pretty looking!

Yeah Jeff I'm all for brand credibility also, I'm not a big fan of the V10 Challenger DP having that "Torque-Glide" trans...

I'm not a fan of the new Camaro at all, but yes it is good GM coming to the plate....

Yes I do actually Ed, I think the CJs should use C4s and the Mopars 904s but that's just me.

One Question ? What Teardown ?? How many times has HP been hit and someone gets a teardown because of it ?? lol

When the 5.7 Challenger went 1.24 under at the points meet in Joliet this year Keith and Dave took it apart and Travis Miller conducted the inspection.
