Most head and cam packages out there push about anywhere from 410-425rwhp on 6-spds.

If I were to buy a heads and cam package with those numbers would I be able to beat a 2002 405hp Z06 ?

Mods that I have so far:
Corsa exhaust
slp y pipe
airlid w/knn
160 stat
hypertech 160 powerstat setting ONLY.

Keep in mind the horsepower is not the only thing that counts. The Z06 is much lighter.

Also would I be able to beat a z06 if we raced from 2nd all the way to the end of 4th gear (should be about 148mph with cam extending the rpms)? I would like to know about both 1/4 mile performance and street racing.

Thanks for the help.

forgot to mention 1 more thing.

I want to stick with ET streets tops. No big a$$ slicks.

As much as power..driver ability has A LOT to do with who wins...!

I have a 2003 Z06 and it feels comparable to the old H/C headers 4.10 combo that my 2000 SS had.I think a stock Z06 will run with or beat an average H/C F-body.Driver makes a HUGE difference with stick cars.

For what it`s worth, I beat an `02 ZO6 this summer with just the mods below. Don`t get me wrong it was close. 12.3 @ 110 to his 12.4 @ 114. I cut a good light and he just never caught up. He had a few little goodies but no real mods. I`m sure his car had more in it but hey, I still tripped the light first!

H/C Fbody should kill Zo6 for any year, unless he has no traction at all. Most H/C cars run at least mid 11's. How many Zo6's do you know that run mid 11's stock?

No kidding... I don't know that I'd want to go on record saying that "most H/C cars run at least mid 11's" but I would think they would certainly be deeeeeep 12's and high 11's in most cases, regardless of driver. Additionally, consider the fact that when you're comparing the 410+ hp the H/C cars are making to the 405 the vette has, you're comparing RWHP to Flywheel HP.

I can understand a head and cam will give much better power but mid 11s???? No way. Unless its with some huge slicks. With ET streets it will definetly be a tough one

1999 SS M6, you are correct the heads and cam would give you 410-425HP ON THE REAR WHEELS. And the Z06 is rated 405HP on the flywheel just so you guys dont get it confused here.

02 Silver Z , at the time of the race you ONLY had a converter, LT headers, and heads and cam? Impressive. Nice numbers.

422 SS, I would also put my money down on the Z06. Especially the 2002+ models.

I knew the race would be so close. Damn Z06s.

Ill post a poll make sure you guys do the voting
Thanks for the awesome responses.

Remember NO HUGE SLICKS ON ANY!

I want to be able to drive to work and around town with this car.

ET streets will be the best I could do.

A Heads cam car on some nitos should do the trick
with after market exhaust wich i dont have.

With both drivers being equal it will also depend on how mild or wild of a package you went with. My cam was a little mild so I could pass Md. emissions. My best time on Nittos was an 11.98 @ 118.xx which should beat most stock Z06's.

Who needs heads and a cam to beat a ZO6

My Stock Z06 run very well in comparison to a H/C Camaro. A lot has to do with the driver. 410-420 RWHP, but at what raceweight? 3600+ lbs? at 10 lbs per HP you are looking at quite a bit. My Z06 weighs 3021 without me in it, and 3250 or so with me. Lets assume a 300 lb differential. Thats 30HP minimum. Also, keep in mind that the M12 has deep 1st and 2nd gear which is like having 3.90's in the car. My car dyno'd 356-359 RWHP. So, basically you are loking @ around a 10HP delta, but stock vs stock gearing is on the side of the Z. Now, you said stock. Keep in mind that an airbox swap, or the removal of the stock lid will put you up around 15HP. In my case 372RWHP. At that point its in the Z's favor. All of these variables plus driver ability will play into any race...

I have seen a race with a stock WS6(2001)M6 and a 2002 ZO6 stock. Ther ace was from a dig up to about 110mph and an industiral street prior to any building yet. The guy with the ZO6 had only gotten his car about 1 month prior to this and couldn't drive very well. I mean he could shift but not agressively. The other guy in the WS6 opened a can up whoop *** all over the ZO6 because the ZO6 driver couldn't drive. He got beat by 3 cars lengths and was loosing ground as the race went on. By the time the WS6 hit 2nd he had 2 cars on the ZO6. Driver ability has more effect on a race then power with manual transmissions.

Why are you that worried about tires? The person said starting from a 2nd gear roll going through 4th. Right?

91Formula

If you see a full bolt-on H/C car running high 11's or worse it's because they are having traction problems or missed a gear. Also you say "regardless of driver" you got to be crazy, look at all the bolt on ls1's that run low 12's or even 11's. Do you think if thoose people were driveing that they would run 12's? Also when I say most I think 60-70 percent is a fair guess. The rest im sure are capable of running mid 11's but the drivers or suspension isn't.

No H/C for that race. I just had the `verter, LT`s, 16" ET Streets. This thing better go at least 11.90`s with the H/C!

2002_TAWS6

91 formula, tires is an issue for 1/4 performance. I asked about "both" 2nd gear roll and 1/4 mile performance.



Wait a sec. You did mean ls1s with bolt ons AND heads and cam right?

There is no way that a bolt on LS1 could run 11s now could it????????

lets try to give a short answer on that and also try to stick with the post please.

I want to make sure I can beat a Z06 with heads and cam and ofcourse airlid, and exhausts. But to be simple lets just say stock LS1 fbody with H&amp;C Vs. 2002+ Z06.
