Quote: Wow lots of activity here over the weekend! I ran the car on Sunday, intake vacuum was 8-9 inches of vacuum at 700 rpm low idle. I moved the mixture screws out an additional 1/2 turn (now 3 turns out), and switched the vacuum advance to the full vacuum fitting, instead of the ported fitting, and the car seemed to run slightly better, but not much. I've been reading the Edelbrock manual and looking for direction there as well, lots of info and combo's for tuning, but no mention (That I found) on off-idle changes.
I would put it back to the ported position or you'll have to much timing when it's not needed .
I disco the vac advance completely and lock it in full at 36-38* at 2400 and be done with it. If you want a "stockish" look use the 800 thunder.
