A buddy of mine built a notch back mustang with a grand national engine/trans.
Had L60 McCrearys on it. Car looked stock, had a set of Aero wheels on it. Those were like $50 a piece. Thing was so quite didn't even hear it.
With the McCreays and the car turned all the way up( high boost, race gas) that car went 9.40's. In drive around street trim, high 9's. this was back in about 2000.
That car made us A LOT of money.
Those tires flat out worked. But you had to get the right compound.
