first let me just say i always limit my total to 38 with a keen ear for detonation, i'm at 4.125 stroke so my motor actually does better with less advance. you may be fine at 38 or even when the weather is cool, 40.

what slot to set the dist. at.....well actually either one, theoretically with a light car you can use the higher advance slot. personally i would use the lower advance slot, because we probably are not hurting in the power department at low rpm, so why kill the tires even more? right? JMHO
