A while back you told me over the phone that when I get my newly rebuilt distributor from you to buy a spring and weight kit. I remember you saying what color springs to use to help with the advancement but I lost my notes. Please tell me if I should use the weights and what spring colors to use or if I should even use them at all. I have a 1974 Corvette 350 with a mild cam. Other than that, engine is all stock. Thanks Cliff!
