Are you for real?!
This is not about who's right, it's about helping Ben. I'll let you have the last word in this pissing contest, but before I do, I'd better comment on a few things, because people may read this post for help...

Fuel economy tends to improve all over, except at WOT where vacuum is close to zero.
quote:If you are running the stock Ford distributor, follow what Ford recommends
If it sits on a stock Ford engine, then yes. If that stock Ford distributor sits on an engine with wilder cam, intake, headers etc., then it needs another curve, regardless of it being a Ford or an aftermarket distributor. Normally a curve where the mechanical advance comes in faster.

I'm not for or against MSD. I've had it before without any problems, but I read many places that they've let their quality drop. Today I drive cars with OEM, ACCEL and ICE ignition. The only reason I mentioned MSD was that I had their instructions close by, and I thought that seeing in black and white, that a major vendor like them clearly states that vacuum advance should be disconnected and plugged when setting Total Advance, would be seen as a valid argument.
