Yes the Z28 was 3 sec. faster than the ZL1 at Milford. Even better yet it was 6 sec. faster than the GT500.

What? Going to a semi slick alone will make up 2-3 seconds compared to a street tire. Cmon now, don't let your love for the car cloud your judgement.

I have no interest in this debate regarding both Camaros and which one is better, pretty funny imo, but we can all agree that tires alone WILL get the ZL1 closer to the Z/28 time.. right? Lets say 1-2sec tops.. MAYBE... hmmm pretty close hu? We can all mod these cars to perform the way we'd like, faster, suspension, uprade brakes....whatever.. Point is these are 2 of the best production cars chevy offers for Camaro fans everywhere, imo...

To each his own. I do have a Z/28 on order, and admit that the ZL1 has fearsome power. However, the Z/28 will brake far later and carry a lot more speed through the corners. I don't think the tires alone will bring the lap times up to the Z/28. IMHO, of course...

Opinions are one thing. There are many tests on this scattered through the internet.

I'm willing to bet that the z28 will run as quick as the fastest manual zl1 once they are put on a real track. All the good zl1 times are from auto cars. Sad part is we won't see many z28's on the strip.

Amen to that. Cars are tools; if the 1/4 mile is your thing the ZL1 is your car. If the road course beckons, the Z/28 is tough to beat at twice the price.

If, however, I had to drive 2-3 hours to my favorite tracks, then I could see the appeal of the ZL1. Luckily, I can hear the NASCARŪ boys when they run Sears Point. Not too far away, though Thunderhill and Laguna Seca are a bit of a trek...

I love how the zl1 is now the "drag" car when this time last year it was the "track" car. I'd drag race and road race both of them but I'd rather dd the zl1.

But guys, this is a drag racing thread. Back on topic. Who cares how the Z/28 runs on a road course? LOL.

Holy crap, Road and Track ran 12.2 @118.3! Those are ZL1 numbers. I way underestimated the Z/28. It is an easy 11 second car with DRs. And now I do not believe 505 at the crank. I call BS on that number.

Not only that, but there are not many ZL1s that have run faster than that with stock tires. And I would think most of them are autos. Road and Track does not pride itself on drag strip acumen and doesn't make up times like Motor Trend.

So if you are thinking of racing a Z/28 with your stock tired and motored ZL1 you better be on your toes.

Fun facts:

The ZL1 @ 4150 pounds and 580 HP is: 7.1 pounds per HP.
The Z/28 @ 3850 pounds and 505 HP is : 7.6 pounds per HP.
The Z/28 @ 3850 pounds and 540 HP is: 7.1 pounds per HP.

They fooled with everything else, why not the motor? Just better flowing cats, a good intake, and an aggressive tune would do the trick. Can't wait for the dynos. Long live the new king.

So much for the z28 not going down the quarter mile. Callaway seems to think differently.

How many times does this aftermarket conversion have to get marketed in this forum?

The real issue for the Z28 will be if the car will really hold up to drag radials an such with the lighter weight road racing components.

for drag racing the Zl1 will alway be a better choice is is just more druable and easer to make big power. ohh and cost 20k less.

That is one reason the z28 is not a car I am just in love with. they have cut some corners that makes sense for its aplication but for a just a toy driver time will tell.

when I was shopping GT500's it has soem of the same issues. clutch and axels are pretty much a coin flip at stock power if you really push the car.

every car has it strenghs and weaknesses. If all I did was go to a track and road race my car I might be looking at one. that is why I shopped the GT500 as well when I bought even though it did not seem as balanced 11 second passes are cooler than 12 seconds passes every time ha ha. it can't be argued. once I started seeing clutch and axles would proabably be needs those cost as much as pullies and power on a zl1.
