Well, the ongoing issues with the Mallory ignition system continue...the car is still not on the road. EVERYTHING except the distributor housing had to be replaced, distributor cap, "shutter wheel", electronic control module, ballast resistor, even the $100 coil...and I added a Mallory voltage spike protector to keep it from happening again. MUST have been some sort of catastrophic voltage surge.
Anyway, as long as I was into the distributor I thought I might customize the advance curve, so I am seeking suggestions for a curve for street use. I have never raced the car.
It has just the internal Mallory mechanical advance mechanism, no vacuum assist.
The kit from Mallory includes "spacers" (for lack of a better term) that will allow for adjustment of the total advance supplied by the distributor's advance mechanism, as well as a variety of springs that will adjust where the advance starts and the curve each supplies.
I would also like to know what kind of total advance figures people find helpful. I believe this to be a box-stock 5.0 HO long block from a '89 Mustang GT and modifications include an Edelbrock Performer manifold, an Edelbrock carb (575 CFM if I am not mistaken), the Mallory Unilite/ProMaster coil ignition system, and sidepipes. Like I said, it's not raced (yet), but I do like a spirited run to 90 now and then, so high-performance street use is the target. Total advance is adjustable by manipulation of initial advance and the total supplied by the adjustments the shims make possible. I do have a good Craftsman timing light, but it is not the newer variety that will display advance figures.
Thanks for whatever suggestions you can provide!
Cheers!
