don't think im putting the C5 Z06 down, i love them, i had an 01 Z to me it did seem to handle better stock for stock on the back roads and was more fun on the back roads since it was a manual.

Z06 is cheaper. My target of 425 at the wheels isn't hard to get with either engine. I wish I could afford a LS7 C6 but hey I'll just have to build an 03-04 up to the 505 flywheel power that it has. Not a hard number to reach with a LS1/6/2. You say it handles better. Maybe you can answer the question I asked earlier on what the difference between the base and Z06 is other than just mere HP.

if you want a bunch of good info come to the corvetteforum.com thats where i stay most of the time (my screen name there is dicky) and there are a couple of guys that are faster than me with just bolt-ons like LS1LT1 in this thread.

well you also have to think about my car is an auto with a high stall and lower gears which all effect the dyno numbers. also the guy said his dyno was reading a little low so he figured add about 10 or so, whenever i get it back and get the electric water pump on then ill probably go and redyno it, ill be expecting to be around 385 to 390ish.

With mods I have heard that the rear end does need some beefing up, but too me that's not "a lot of trouble" as just about any car I would build the rear end would be on the list of things to mod.

OK, here we go...
Obviously you don't know much about C5Zs. My 02 Z06 weighed 3080 with HRE wheels and crap in the trunk. With stock wheels and nothing in the trunk it probably weighed about 3050 or maybe less... Can't go by curb weight because those numbers are always bullshit. My current 03 Z weighs less than my 02. I'll get an official number for you Friday when I go weigh it. It's currently stock other than a Vararam and shifter. (Note that the Vararam is definitely heavier than the stock intake box.)
Next, the C5Zs may be "rated" at 405BHP, but they're obviously under rated since they dyno between 360-370RWHP consistently. Do the math: 360 x 0.85 = ~423HP. These are consistent numbers so don't tell me about what a GM fact sheet says. Real world numbers are better for bench racing.
Um... An LS6 is not a mildly tuned LS1. They're totally different in stock form. Cam, valves, heads, intake, tune, injectors, etc. The LS6 Vettes make 60HP more to the ground than LS1 Vettes. A fully N/A LS6 can make over 500RWHP with supporting cam, heads, manifold, and exhaust. I've seen it although it's not very streetable. Sorry to say, the LS2 isn't that much better. The displacement isn't that much more over a 5.7L. Look at the LS7. You really need to go to a 402 or better when you want that kind of power to the ground and still be perfectly streetable. (Especially with a manual).
You should take a look at the fast list for stock C5Zs. (http://forums.corvetteforum.com/1557690447-post2.html)
There are C5Zs in the 11s completely stock. Power to weight ratio plus the MN12 transmission gives the C5Z a HUGE advantage over the LS2 C6 Coupes. The C5Zs are geared to the equivalent of 3.90 gears in the diff.
OK, you ran 12.58 @ 112MPH. That sounds like you got a great launch. The C5Zs are rated at 12.7 @ 117MPH. You're going to argue that the LS2 Vettes are faster?! Again, look at the fast list for bone stock C5Zs. (http://forums.corvetteforum.com/1557690447-post2.html) Notice there are plenty of them running much faster than your LS2.
Sounds right to me. My C5Z weighed 3080Lbs as well and that was on heavier after market wheels and half tank of gas.
Really? Actually the weight of an 04 Z06 versus an 05 LS2 C6 is within 100 lbs so I wouldn't call that a significant difference. hmm. With a 200 pound driver and a listed curb weight of 3179 and 404 flywheel horsepower at sealevel the car should run in the neihborhood of 12.50. What is the real difference between the Z and base other than horsepower? They weigh nearly the same. Was looking more toward an 04 Z anyway. Although from what I'm reading on em the LS6 is just a mildly tuned LS1. Please correct me if I'm wrong but that's what I'm seeing. I think I could just go with an 02-03 base LS1 and build it from there and come to the same power potential as the LS6 for essentially the same money meaning that the LS6 ceiling N/A is about 475 RWHP. Just my thinking. Please feel free to call me retarded if I'm wrong.
Next, the C5Zs may be "rated" at 405BHP, but they're obviously under rated since they dyno between 360-370RWHP consistently. Do the math: 360 x 0.85 = ~423HP. These are consistent numbers so don't tell me about what a GM fact sheet says. Real world numbers are better for bench racing.

uncles 07 a6 ls2 c6 ran 13.0@109 had the base gears and stock run flats with intake and catback made 345whp before tune and after 355whp.
but look at dicky98z he has full bolt ons and still didnt make more than my dads ls6 z06 with just intake and tune which weighed 3080lbs.
get the ls6 z06 imo

i honestly do not believe stock for stock the ls2 is near as fast. if any ls2 c6 wants to test it out in the bay area im down, i 100% believe i will win by atleast a 2cars

LS3 C6s are a drivers race against LS6 C5Zs. That's already been proven time and time again.
I'm going to be at LA Invasion so I'll post up my times. I've never either of my Z06s on the track so this will be my first runs. I'll be at Irwindale tomorrow to practice launching.
I'm not the best behind the wheel, but I did manage to get better times with my dad's manual Solstice GXP than GM stated and that was at high elevation. I'm hoping to run 12.5 or better.

Been a long time sine I've been on this forum or driven my Vette since I left May 15 last year and still overseas. However, in my experience at the track, the 02-04 C5Z is quicker than the LS2 C6, stock for stock and slightly modded. My buddy and I used to run each other quite a bit, his 03Z versus my slightly modded 05 LS2 C6 (mn6) with cat-back, Halltech and tune. Granted, two guys running a dozen times isn't exactly scientific. Also have a half dozen runs against a guy who had the zip tie mod and drag radials vs my car with VR, FAST, full exhaust, tune. Though he was a much better driver, it still took quite a bit for my car to best his 1/8th mile ET's (my mph was about 3 mph higher). Here is the list of stock LS2 C6 times from CF:

This my car now with a VR, FAST (non-ported), 1 3/4" long-tubes, x-pipe with cats, cat-back, tune and Comp Cams 230/236 .613/.608 113lsa on XFI lobes. I don't have any decent track times with this set-up yet and this cam really requires gears as my low kind of sucks so 4.10's are going in if I ever get back to the US

It's kind of amazing how different each car could be even when they're show room stock. In theory an automatic of the same year should consistently run the same times as it's exact equal. Of course, driver weight, DA, etc have much to do with it... But even a full second is pretty crazy.
I didn't get to run yesterday. Friends all backed out last second. But I'm still in for LA Invasion and I may go Thursday to the 8th mile to see how I do.

That's ok, I felt the same way right after I did it, three times in a row. ![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)
Nope none of that involved, just some solid drag strip/drag racing knowledge and good air/track conditions. ![Nod](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_nod.gif)
I don't know what they "should" or "shouldn't" be running but 1) the base C6s do not weigh significantly more than the C5 Z06s (maybe even within only 100 pounds of each other depending on options) and 2) what is this rated 12.7 you speak of for the C5 Z06?
The best pass for a bone stock C5 Z06 is an 11.78, over 4/10ths quicker than my C6's bone stock 12.21.
