I'm trying to find the "sweet spot" with my SB Ford 8479 MSD Pro Billet distributor. I set it up a year or so ago using the one heavy silver/one light blue spring and the blue bushing, if I recall correctly, and gave it 9-10 degrees of initial timing for what looks like 30* - 31* total. Since most of my driving is at 65mph or less and at less then 3000rpm, this doesn't look like it will give me much advance, i.e.~15* @ 3000 for my mid range acceleration and, in today's world, economy.
This brings me to my question - would it be better to speed up the advance, for instance, use the "E" or "F" settings**, based on the instruction graphs supplied with the distributor or am I going to be getting into the detonation (ping) world at low RPM with too much mid range advance - which I try to avoid. I don't race but do kick it in the butt occasionally, so am not looking for continuous top end performance (yeah, I know, I'm not normal :nono: )
Engine/car specifics:
2400# '31 Ford roadster w/SB Ford 5.0, SVT 'E' camshaft w/1.7 rockers, GT40P heads, Edelbrock Performer RPM intake and 1405 Performer carb. all going out through a 3.25 rear gear and 29" tall tires and trying to run 87 or 89 gasoline (cheep)
**Here's a link to the IB information.
Yes, it does run fine now, but could the engine be just a bit better. I'm doing the carb too as it is a bit rich. It was set identically to the one on a long gone but significantly warmer 351W
