Thank you for the info. The 250 currently has HEI, but I need the TBI style distributor for a plug and play to my current harness. This should be a very quick, and efficient, way to convert the inline 6's to factory TBI, using stock gm pieces. I also forgot, I will need to swap over the shaft "stator " from the 4 cylinders 4 leg piece, to the 6 cylinders 6 leg one.
