Hello everyone, I am on this site continuously and I am debating a purchase. I sold my 05 GTO a couple years ago and will be purchasing something within the next couple months. I love the 07-09 GT500 and how easy it can be modified. An old rival just bought a C6 Zo6 and he is talking smack. the car is stock, but he can drive. I've been looking at the 1/4 mile times here and the corvette forums. I am considering an 07-09 Shelby, A6 C6 ls3, or 2010 Shelby. If i purchase the older shelby, I want to put a Wipple 2.9 and supporting mods, including drs and suspension. But, if I purchase the 2010, mods will have to wait because of the down payment. If I purchase the auto LS3, I want to supercharge it through ECS. The Auto would be very consistant if I raced him. Most are seeing a little over 500rwh. The price to mod both are simular. I love the fact that you can put 20 inch wheels on the Shelby with Drs, lower it and it looks good. the vette needs the wide body to really look good (imop). It seems the Shelby needs 700rwh to see 10s, because of the weight. Some Zo6s have run bottom 11s stock. I know, with a ported Eaton, pulley, CAI, and 3:73s the Shelby can go deep 11s, however, the heat soak will become a problem after a few runs. I know every one has a Vette and I barely see Shelbys. But, the Vette is really hard to turn away from. I am not new to Stangs. I had 4 all modified, 2 with superchargers. I also had an 86 Grand National that ran 11s, a LT1 T/A, and My GTO 440rwh and (560) with n2o. I did consider a used Zo6, but now thats out the question. I am a good driver, I drove my GTO 12.7 @108 with just Drs consistantly, before I added the cam. Sorry for the long post, but I need some bias advice LOL.
