Thanks for that link.
It looks like I could get a well built C6 from them for about $1100, or I could buy the adapter kit to swap my trans for a 700R4 for $800. But then I would have to get the 700R4 rebuilt and I'm not sure what that would cost. Which way should I go on this, the 700R4 and adapter or the C6?
I want my car to run atleast 120MPH and I am running 18 inch wheels with 275-35-18 rear tires. I would like to get a locking type rear carrier that will bolt in my original rearend, but what gear ratio should I run with my tire size and either the C6 or the 700R4 to get the mph I want? Another thing...if I went with the 700R4 would the speedo cable work?
Thanks!
