I'm wondering what most of you 427 FE guys are running for ignition timing?

I think my distributor is a MSD Duel Point that was converted over to a Petronix. It doesn't have a vacuum advance, just mechanical advance with adjustable stops.

When I got the car the (base) timing was *severely* advanced. I set it to spec (8*) and checked the total timing. With base at 8d, total is mid 20's. I set the total up to ~32d and base is looking like it's between 10 and 20 (15-ish).

I ran a quick search of this forum and find most are running between 36 and 38 total. I can adjust the stops so I get more advance allowing me to set my base back to spec, or there about.

I'm limited to "mountain" formula 91 octane Premium gas. As most know, hearing detonation or pre-ignition with loud pipes is pretty much impossible so I can't tell you for sure if it's pinging or not.

Right now, I'm just picking brains.


Thanks In Advance,
