i'm a 3.73 guy with a c4 all day long. imo if you start really modding the car and intend on racing it a little you will run out of gear far before the 1320. If i could talk you into keeping the aod talk to freddy brown trans in new york. they do aod's for randy seward's car in Tennessee. he drives his car to nmra and last year drove over 2000 miles to a true street race averaged 8's in the quarter and drove it home.
Now that is a true street car. i love the over drive but is far as i know they are very expensive ti build, right? i have to stick to a budget but im interested so i will check it out..thank you
