Help, I just got a hei from whites perf. for my sbc 355. A great deal! I wonder about the curve. it,s got the 65k coil,and other mods but does it have a performance spark curve. it has the adjustable vacume adv. What do i look for to set the optimal curve. I read some old posts about the subject. I am going to set the timing at 3000 rpm. then turn it back to stop detonation. after that what am i looking for. what should timing ge at 3000. THANKS I love the info i get at this site. Its the greatest!
