The overdrive 4th definitely isnt optimum for racing, but it might work ok depending on rear gear and end MPH. Caltracs are a good investment, but rear tires are probably even more important. It doesnt take anything special suspension wise to run 12's... I think your gonna need a bit more power though..

A mild modern camshaft like a Comp XE284, RPM intake, and a 750-850 Double Pumper would probably get you where you want to be.
