Is your Chev distributor mech advance only or also with a vaccum advance unit. My 8BA is fitted with a Chev distributor along with a vaccum unit. Both can be adjusted courtesy of Charlie NY and it works well.
I understood the bump on the pulley was at 4 degrees BTDC.
Mine has around 8 degrees vacuum and 22 degrees full mech advance.
It runs well at this set up. Previously had too much total advance about 38 degrees and the fitting of mech adjustable advance stop and same at vacuum unit was able to reduce down to 28 to 30 degrees total.
