Hasnt been since 1970 that a car this fast graced the track like that in stock form. I beleive all it took was a set of tires to get the '70 vette into the 10's bone stock with its 427.
It just goes to show that mid 400rwhp and a well balanced car is all it takes. I imagne gears would do the trick to drop te 60' slightly and make for consistent 10's.
Did you think the clutch was at its limit dropping from 3500-4k?

Great times for the 60's you are cutting. I drag race a 02 Trans Am with an LS1 and cut 1.5 60's with a best of 11.6. You must not be getting any traction even with the DR's.

Nice run, Ron.

I'm not sure exactly who you mean, but it was cold & tough to stand around & watch many guys run....
It was VERY close, if not already there.
It couldn't take a 4000 launch from me...
I actually DID get traction...
The clutch limits the launch. I used to launch at 6300 on my RPS clutch in my C5Z. If I had that clutch on this car it would be 10.7's or better all day long!
The launches are linited to 3500-3800rpm's because of the weak clutch.
Thanks!
My car WILL run 10's in more ideal conditions & a little more seat time for me on DR's...

My brother had a 427 435 hp '67 Stingray with a roller cam, head work and headers, and I doubt that car, as fast as it was, would have ever seen low-11s much less 10s. Someone might prove me wrong, but I'd have to see real evidence that a '70 with a 454 390 hp (427 replaced by 454) could have hit 10s.
Nice run, Ron.

I didnt think it would be so sensitive a topic. Anyway, from the mag I read and give no statement of legit facts or proof, nor do i care:
Any 69 ZL1 is easily capable of 11s with any competent driver, and running on drag slicks, can easily run deep into the 10s. The quickest documented ZL-1 was a 10.89 @ 130 by Motor Trend in 1968. Some people thought it was 10.60 @ 132 documented by Motor Trend in Oct 69, but that was actually the same car with a prototype LT2 454 motor. (additional details of this can be found in "Classic Corvette, The First 30 Years" by Mike Mueller, Pages 313 - 319, 2003 edition, published by Crestline - MBI Publishing Co.) Zora Arkas Duntoff himself claimed 10.5 on slicks. As we talk about tires, please remember, this is 1969 technology. Slicks of that era were not as sticky as some of today's radials that we find on some sports cars. On top of this, the ZL1's top speed with stock gearing was close to 200 mph, and it could easily go beyond if the gearing was changed.
I beleive the stock gears were 3.07. The above test was a geared car with 4.88's I beleive. Anyway with street tires or slicks of the day aside, my point was it took this long with our current technology to produce a car in kind due to business practices. It wasnt to say the old vette was faster and offend anyone.

Amazing rather than agree the Z06 is a beast and that the '69 ZL1 was awesome for its time I get bashed for saying something nice. Lets try to keep in mind that I didnt write that....it was in an article. Beginning to feel sorry for offering the pat on GM's back but I'll try again.....
The technology to make a 10 second all motor street car has existed for 37 years, yet it took until 2006 for GM to produce one for consumers.
Persoanlly I like the white one better.

2 additional facts I just heard from the old man.
1-69 of the 1969 camaros were also "1969 zl-1's and all could do 11 second runs which may be what the article was referering to. It may have been what promted GM to create the flagship cars higher performance level so junior couldnt beat it.
2-30 of those 69 were returned to GM that couldnt be sold in 1969 and werent sold until 1970. No demand?
