L-89 TUNING TIPS. . . HELP

[justin_18_ky]

well, its true AV fuel. . . a local motorsports place sales it. but it i'm using a 70/30 mix. . . 70-av/30-93 octane. . so i'm looking at 108-110 octane. i haven't checked the plugs since i put them in, but they only have 15 miles or so on them. what do you reccommend for the gap settings?? its the stock coil, so i can't go too big. the powervalve was a 6.5 and after having the carb rebuilt by a 'so-called' professional, he said that it was too big. i only agreed with him. but i thought that a 6.5 would be fine, considering the vacuum is about 10 hg.

so you think that the 16 degrees initial would be fine? and 39 total would be best? what if i dial up 40 and there's no detonation? the proper valve settings are .024/.026 for the aluminum heads. i'd like to go a little tighter for the upper rpm power, i'm running .025/025. . . so i'm thinking about .023/023. . .
