Re: Which Factory C4 was the quickest? (rick lambert)
If you limit it to only those cars that rolled off the B.G. production line and not the "tuner" cars like the B2K Callaway twin-turbo, then I would think that either a LT-4 powered 96 or a ZR-1 would probably have the best times. The 90 ZR-1 was probably the most powerful of all the ZR-1's (just my HO, no flames intended to the later 405HP crowd :D ) but from what I have read and heard, some of the 90 motors had wide ranges of power output from the factory, apparently from 350HP to over 400HP.
Lots of magazines did 1/4 mile testing and they all got different results. Driver skill, weather, track conditions and such all would play a part.
How can you call the 87-91 Callaway Twin Turbos a tuner car??? It was ordered from the Chevy dealer with Regular Production Option number B2k. If you want to call it a tuner car, youd better do the same with the ZR1 because Mercury Marine built the motor for that car as well.
And yes the 88+ Callaway was the quickest and fastest of the C4s.
The ZR1 was in house doesnt matter that MM built it and the only reason they did build it is because they were are experts in low producion motor assymbly lines.
It was cheaper to pay MM to do the work than to take GM power train and set it up to build the LT5.
When the ZR1 and the good old L98, LT1 or powered cars rolled off the assymbly line no matter if the B2K option was selected the ZR1 wins, then even thought it was a RPO code the callaways were done out of Gm and is there for not a assymbly line function but it was a option so its kinda hard to call it
If you mean totaly stock car the way GM ment it to be with no outside modifications the its the ZR1 hands down.
then even thought it was a RPO code the callaways were done out of Gm and is there for not a assymbly line function but it was a option so its kinda hard to call it
Actually there was a special build for Callaways on the line. It was Z5G, I believe, I'll have to check when I get home. But it was a special build function that group certain options together regardless of what other options or lack there of were checked on the order.
Bottom line is...Chevy couldn't build a TT Vette they needed help...nor could they build the LT5 motor as it needed to be done, they needed help.
If those LPE 427s at the pland had made it to the 50th Anniv cars, would it have been a factory Vette or LPE car?
Re: Which Factory C4 was the quickest? (rick lambert)
I dont consider Callaway cars to be factory GM cars. What would Mallet or Guldstrand editions be considered?
I can always go to Callaway and have twin turbos installed in my car but I cant go to GM and say build me another ZR1. That is the litmus test for factory built.
I think the main reason people think of the Callaway TTs as tuner cars is in the name. The car carries the Callaway name. Same scenario with the LPE cars. If you tag it with the tuners name 99% will call it a tuner car, no matter if it had a RPO listing.
They should have just called it the Twin Turbo Corvette.

BTW Callaways are beautiful beasts.
Thanks for the compliment, but Callaway is done with the turbo biz. Youd just as soon get another ZR1 built as a Callaway TT.

I dont doubt they did something special with them Im sure it could have been in wiring and such..
what about the corvette challenge cars?
Did you know you could order a corvette of the line without a motor installed?
I dont know if its fact but I read it somewhere might be a erban legend :D
