vacuum advance

Yes, its an MSD E Curve dist and i have the switches set for lockout. The nice thing is the start retard which backs off the timing 20 degrees while cranking, once the engine speed hits 500 rpm or more then the retard is off and engine has 34 degrees all of the time, no matter the rpm. Works great, now if it had a stock converter and 2.73 gears, I'm sure the motor would ping at low-lugging rpm's
