For the love of humanity, don't drive a modded ZR-1. Stay away from these evil machines. You will never forgive yourself for taking the dark path. There is no return.

It would take a stroked lt5 to take one on.

My experience exactly. I had no problem with C5's up to and including the 01' ZO6's, but the 02's with a little more HP and the light weight could edge me out.
The C6 ZO6 LS7/427's?.... Fugetaboutit

I guess Marc has to work his magic before I tangle with any more 21st Century Corvettes.
I guess we still have bragging rights to "The fastest American Production Car of the Twentieth Century", don't we?

If I was more concerned about speed I would have not sold my c5 corvette. Speed isnt everything. History, engineering and a limited edition product is sometimes more important than speed. I like the fact that I have a rare car, that is unique, looks great handles and performs with contemporary cars but will be 25 years old in a couple of months. Our cars are still relevant. They are not the fastest unless we dump thousands of dollars to boost them up which I will not. Maybe a nitrous shot if you dont mind losing a head gasket or worse.

I am satisfied with the Lt5 performance and happy about everything else. This has been the car I have most enjoyed owning and driving. It is not the fastest car I have had by a long shot but the funnest.

I agree with ^^. It definitely isn't about speed for me. I had enough to pick up an 08 ls3 but what a god awful ugly car in my eyes. I knew it was similar in straight line speed but the dollar/speed ratio is obviously much better with the LS3 motor when it comes to heads or even a cam or a stroker.

I always like to say. "its not about how fast you go. Its about what you go fast in' !!

Should be:
L68 1967-69 400hp 3x2bbl.
L71 1967-69 435hp 3x2bbl.

No Mark IV was ever released with dual four barrels.

I have one of each–1995 C4 ZR1, 20014 C5 Z06 and 2012 C6 Z06.

My ZR1 is modified to a hair over 500-hp. Big deal back in 97/98 when Van Dorn and I did the motor but not such a big deal nowadays, I s'pose. The C5 is making about 445 though mods–CAI, rockers, X-pipe and calibration. It's just a hair quicker in an eighth than the ZR1 mainly because it weighs quite a bit less. Beyond the 8th mile, the extra horsepower begins to help the ZR1 catch up.

As for the C6...no contest. The 427 is quicker and faster–and that was before I started modifying it. Right now, the backdated exhaust, cooler ECT and some cal work has me at about 515. Plus, the car is easier to get off the line because it has launch control. Enable launch control, bury the gas, quickly release the clutch then keep your foot on the floor and shift. The most fun I've had in a street car, like...ever.

What is your opinion about the failing valves and valve train isssue? I have been looking into swapping into one?

[XfireZ51]

No question newer technology is awesome. However, I would love to see GM repeat or beat what was accomplished by the ZR-1 at Ft. Stockton.

Thanks Hib!
Of course, I forgot about the 3 x 2 bbls.

Corrected!
