"Plain Jane" 1970 Nova Build

[Chuck_Burg]

With that much power, I'd go with a G Force 4 Speed. My buddy broke his M23 twice with a 700hp 496 and slicks and 4.56 gears, no clutch tamer.... My M23 has held up well at the track, but only has around 12 passes, I'm guessing my 496 has around 550hp. My M23 had to be repaired by Autogear twice under warranty because of quality control issues. If I was going to do this allover again, I probably would use something beefier.
