What pills are you guys using with your edelbrock spark boxes? I've read some like #1 and some like #3 but does anyone know what the difference is? I've got a fresh LQ4 with a crane 228/232 cam and I have #6 in there right now. I'm just about to put on some break in miles so I need the curve that is easy on the motor. don't want any detonation. I was thinking of putting in the #1. I've tried a few and so far they don't change idle characteristics.
