You have a clutch listed then at the bottom a built automatic, is this built automatic something other than a trans?? Don't know what it'll run but if it's an M6 and yer gonna run at the track alot then I'd suggest investing in a 9" rear.

Ditch the 10 bolt and 3.73s. Go with a 12 bolt or 9" and some 4.10s.

it gonna be a daily driver and will look into a 12bolt or 9 's when I get $$$. For the moment the 10 bolt will have to do.

242/248 duration is pushing the limits of daily driving

it an auto bro, will change it to m6 when tranny goes out. Is the cam right for my setup because it a grind cam. It will be mostly weekend but need it for a daily driver in case my hooptie dies.
