When you start making changes to stock wheels and such does the car have to be re-certified in the crash test area as well as normal validation procedures?

From what I have read the slightly lowered versions of that other brand muscle car did not require crash tests. My guess is that a small change in wheel diameter would not require more crash testing. Wheel validation yes, but I don't think crash test. Perhaps #3 can give us an idea of the ride height variation allowed in crash tests.

Yes...which the ZL1 validation will accomplish...
BTW, if Wixom is viable building LS7s in the realitively paultry numbers they've enjoyed with Corvette, does it make sense to continue if volumes ballooned to 3 or 4 or 5 TIMES as many units as might be the case with a Laguna Seca-seeking and -priced Z/28? And there IS "value" in "shared costs"... |

The LS7 has probably the same life expectancy as the 5Gen, itmakes sense to marry them.

The sticker shock of an LS7 powered Camaro would bring many of you back to reality.
Plus, the LS7 was designed for the Z06. Your not going to just plop it in a much heavier vehicle and be happy with the results. To do it right you would need to optimize the cam and torque curve for the heavier Camaro. Which leads to why the LSA was chosen over it in the first place for the Camaro performance version.... later named the ZL1. The supercharged grunt is more matched to get that weight moving vs a high revving motor. If you remember the C5 Z06's. They screamed with the LS6. I owned two of them and they were a riot to drive. Then they put that same LS6 in the tank of a CTS-V. When I drove one of those, I couldn't believe it was the same engine. Pulled hard at the very top of the revs, but the weight just killed the low end. Had no where near the excitement of that engine in the lightweight Z06. Fast forward to the next gen CTS-V.... and do you see the current Z06 engine in that car. No. They got smart and went supercharged with a better torque curve to match the weight... and the CTS-V is now an out of the park hit. That's from engineering an ideal powertrain, instead of grabbing something off the parts shelf. |

A Gen-1 CTS-V weighs about the same as a Gen-5 Camaro. But comparing an LS6 to an LS7 is like comparing an LS7 to an LS9...100 hp and an equal amount of TORQUE...
I have experience with an LPE-prepped C5 TT LS6...which eventually was replaced with an LPE-prepped LS7. The LS7 with 540 rwhp turned better times in all disciplines than the 597 rwhp TT LS6...something called "heat-soak" took over the TT, and that 150 lb. on the nose was very discernible... Sound familiar? |

I'd taket that bet.....................unless a Tim Horton's donut is gambling slang for $1,000. The original C6 Z06 volumes were up to 1/3 of total prodcution or about 10,000 units per year. So when you say, "ever" do you mean total Z06 production? or highest year of production? Nowhere near that right now, of course. But that would be a benefit of using the LS7 here. It would get back to production volumes. Quote:
It is less, but far from ZERO. Quote:

Also by your math, are you assuming 30 to 50,000 Z28s with LS7 power? That's 30 to 50% of annual sales. That's pretty hefty considering the car you wan't to compete with sold 4,000. Quote:

Number 3, we'll find out the depth of our relationship @ Woodward this August... You DID say the first Michelob was "on you", didn't you?! The 2nd and 3rd...waiting for you!
Current Z06 vs. potential Z/28...and I predict 10,000+ LS7 ZEEs (which is several times current Z06 volume). Ford is "constrained" (their word) to a total of less than 5,000...4,000 "Base" and 750 LSs, according to "plan". BTW, 1969 ZEE sales totalled 20,302 units. '69 BOSS 302 = less than 2,000...'70 BOSS 302 = 7,000 "If you build it, they will come..." Last edited by LOWDOWN; 07-12-2011 at 04:43 PM. |

Pete, you mentioned heat-soak in your Pedder's S/C Camaro...it's WORSE with TT...and the Shelby just may find that out...
