OK, I tried to search, and have gleaned that ideally, for a stock, "low voltage" ignition system, .035 is a good gap for original or slightly modified ignitions.
I just put a MSD 6a on my 68, with performer RPM heads. Edelbrock only lists the size and range, not the gap for the heads. The MSD instructions call for .050 for compression up to 10.5:1.
Pretty wide variation there.
Would it be a safe bet, to split the difference, and gap at ~.040?
