are you just a know it all??? wow, you come off very pompous. ALL street driven vehicles should know what initial is set at. to know what centrifugal advance you have is IMPORTANT. like adam said, it helps throttle response. 57 total? what calculator do you use? i have an msd distributor that is set to 17* initial, with the 18* bushing for a total of 35. is my math wrong?? is my 400hp 360 a mildly modified street car?
i just can't believe how arrogant you come off. are you from moparts?
