It just seems to me that the 2005 c6 with more cubic inches would have the greater mod potential and a more reliable bottom end to work with. Has this been discussed? I've been thinking about building up my zo6 but lately have been hearing about its weak bottom end. I makes sense to me to start with larger cubic inches rather than build my existing one.
What do you think?
From what I've seen so far...the C6 isn't as mod friendly as the C5 is. Not sure why...you would think a H/C package on a C6 would make more power than a H/C on a C5 but, I haven't seen it happen yet. Of course, shops are still in the very early stages of modding the C6 so, I suspect that the numbers will increase in the near future.

The more you mod the less the difference. The ECU in the C5 apparently is easier to reprogram. On LS1Tech, vendor's report 550+rwhp from a 402 LS2 and 402s (4" stroke) are being offered from several sources.
From a performance standpoint, the more you mod you might as well have a '97 C5. One vendor on LS1Tech used a '99 coupe as they show vehicle (I believe they are well into the 9s).
I don't think that the C6 has more "potential". Take your car and if you want to build it up, just do it. Don't go down the woulda', shoulda', coulda' road. If you're going to build up the whole motor, just take the 427 route and you'll be smiling. No regrets.

I think you're right! This is what I will do. I will take 25 grand and replace my 2004 zo6 with everything that the 2006 zo6 will have except for the keychain. I have a really cool keychain with a flashlight.

Jason, I saw your other post about h/c cars, and your concern for bottom end reliability. I am one of those guys who preach bottom end build up first before you do any major mods. There will "always" be the people who have 20k miles on their h/c car with no problems. My overall point here is piece of mind, money, and safety. You certainly arent modding your car to drive like granny goose. You mod your car to be able to use the power when you want to, or when you need it. Whenever you mod the top end of your Z, be it h/c, or s/c, without beefing up the bottom end, you're running a risk. It's not necessarily that the stock bottom end is weak, but when so much added power is placed on it, it carries the burdon of supporting all that extra power. Under certain conditions, something will malfunction. It's like putting 500lbs on a cart with inflatable wheels that were designed to handle 350lbs. You can roll the 500# around on it from point A to B for a while. But it's going to break sometime before it should.
When the situation arrises, when you want your power the most, you are going to want to harness it, and get it to the road with confidence that it wont break.
Cubic inches are always welcomed but there again so it an iron block. And here comes the bottom end issue again. And the Clutch issue. There are so many routes you can take for more power. You have to ask yourself what you want the car to accomplish. Once you have that in mind, do the mod. But as with anything you do in life, do it right the first time.
Basically an LS2 is an LS6 with more compression and a bigger bore. So the answer to your question is YES the LS2 does have the potential to make more power than an LS6 (especially area under the curves).
I think the things you are seeing holding back the LS2 are programming and intake manifold.
Higher compression and larger displacement = more power potential. The bottom end isn't any "better" in reguards to strength. They're tuning is has been really held back b/c LS2-edit is finally comming out and reaching the tuners.
