I have been putting together a HI PO motor with block, heads, and intake date coded 6K. My question is what date code distributor would be correct? Would the Fomoco or Autolite be correct? I see the Autolite with date codes in the 6J, M which are before and after the date on the block and not sure if I need the Fomoco or Autolite. Any help would be appreciated.
