Default Which is the better platform for bigger power

I've been reading about the LS7 having some issues with boost/N02. What would be the better platform to start with, LS3 or LS7? Which is the more versatile/safe for modding?

Any input would be appreciated.

For me, I would go with the LS3 based 08+. One can make power power for less money than a corresponding LS7.

Thanks Keith! That's what I was thinking; but the looks of the Z06 (wider rear quarters, and scoop) look so much better. Any idea of how difficult it would be to add the wider rear fenders/tires to give it a better stance?

I'm 95% certain that the Z06 (any C6) quarters are simply bolt ons. Now whether they line up with the bolt holes of a standard C6 is another story.

The ZO6 rear quarters do bolt directly on. I know of several standard C6 that have the ZO6 quarters bolted on and are running the wider ZO6 rims also.

Hey Doc T, what you got up your sleeve bro ???

Not hijacking Doc but I have to wonder. How would a c6z respond to a built up FI ls3 motor ?? In my opinon the thicker walls should let you make a lot more power with less cubic inches due to more boost. Spray should work well too. Just my 2 cents.

The other HUGE consideration is that with the LS7.... you've got the rest of the car that goes with it.

So you feel that the LS7 is the better platform?

fenders all bolt onto the non-z06's, but like joshua said, there are other benefits to the z06 platform like the materials used to build the frame etc., the z06 will be lighter. otherwise start with the ls3 base

When I was at the Corvette Museum they had the aluminum frame for the Zo6 on display.... towards the front of the exhibit there was a handle on the front of the frame so you could lift the chassis.

The frame was so light that you could lift it with ease!!! Add having a magnesium engine cradle, awesome brakes, engine/tranny/diff coolers, plus being able to pull past 60 mph in 1st gear and past 90 in second......

Not to mention resale value....

When you mod up an LS3 in the end you still have a "run of the mill" 'Vette that's been modded.


The Zo6 is the only C6 I'd buy (can't even think about the ZR1 )

Thanks for the illuminating! Makes a lot of sense, and looking back, it's the reason I wanted the C5Z06 instead of the coupe/vert.

And oh yea...how 'bout that ZR1! From what I've heard, and read, the MSRP + dealer markup will be upwards of near $150K

Get the LS3 if your going to MOD. If you have the cash, buy the Z06 but, if your on a budget,...and want some money left over for MORE mods..get the LS3. The rear quarters, you and your buddies could do in your garage with no special tools. Very easily done. You can then buy different wheels to fit the fenders if you wanted...painted or stock Z06 ones would be nice...or even more custom.

The sky is the limit my friend.

If you're going to mod I'd buy your old car back and put the motor you want in there. If you would leave it stock I'd go with the C6Z for the reasons mentioned above. I know you were asking about power adders, and I love to spray, but I don't have traction until 3rd if it's warm out, 4th when it's cool. I just didn't feel like either C6 was enough nicer to justify the price difference.

Great idea! I actually thought about that, but really, I'm wanting to keep near stock until the warranty is out...need that security blanket until the warranty time runs out; or at least get her paid off.

BTW, looking at your sig, you have a heck uva beast there! 440ci LS7

The LS3 is a better platform than the LS2. The Z06 is just about at its maximum in stock form. Adding more HP is asking for a disaster to happen without knowing when. When GM was looking at the ZR1 for 2009 the knew the LS3 was the only way to go. Even at 6.2L it make a conservative 625hp, think what they could do if they opened the engine up. Even at 427 cid it is still a stouter platform than the LS2.
