Im not sure if this is something that would be permissible here or not, but I've been doing some preliminary tests on an HEI distributor using different centerplates and weights trying to determine what degree of advance is possible for the particular parts I've got on hand.
I had found a chart on another website that gave some of these figures, but most all of them were using just one set of weights.
I have either 9 or 10 different distributors, but 4 are in various vehicles at the moment, so I'm just using what I have easy access to right now, as this started as an alternative method to climbing under the hood and swapping the parts and then running the engine and using gas to find the parameters for a given set of parts.
The only drawback to my current method is that I still don't know at what RPM's any given combination of parts gives the best advance curve.
Im able to determine what the maximum advance is, with the centerplate facing up or down, but the actual RPM's that it begins and ends at will still need to be done on the engine.
The advance springs are also another variable in the advance rate, which would also have to be checked on the engine.
I guess what im getting at here is, would anyone be interested in this limited amount of information for a handful of different centerplate/weight combinations, and would it be permitted here on this site?
