Unfortunately I do not have a plotted timing curve.
The distributor was curved by Don at FBO
Mine is a street application and I believe the curve comes in slow.
I had a MSD pro billet that I had set up way to fast of curve all in by 2500 rpm, that did not work. anything over 32* total it would knock like a *****. With my new FBO distributor the timing comes in slow all in 36* at 3200 rpm and no knock. Then the vacuum advance adds another 10* at cruise for a total of 44*and it never pings.
I would never thought it possible but it works.
and my fuel mileage went up
