292 distributor

[cryowagon]

I'm putting a 292 back in my '64. It had a 194 when I bought it. I'm trying to decide which distributor to use. I have a new HEI I can use, but I'm trying to stay original. I have the original distributor from the 194 (1110293), a distributor from a '66 292 (1110364) that looks like it may have been rebuilt, and a distributor that came from a 230 according to the part number (1110280). According to the shop manual, these all have different advance curves. According to the parts books, not many parts were interchangeable between them. New and rebuilt distributors are all lumped together under one part number. I'm just wondering how much difference the advance curves will make. Does anyone have good specs for these distributors or a parts source? I'd like to keep this thing as close to original specs as possible.
