these are are all the same engine, just names from different years, and how they may have been equipped.... but there is so little written about this model of engine.
I am looking for a lower distributor bushing/thrust washer.... my '87 181ci block was fitted with a bushing for the old conventional distributor with a 1/2" shaft, the new EST distributor has a 7/16" shaft, and so Im looking for the proper bushing for it...
does anyone have a common part number or diagram showing this bushing, which is sometimes called a distributor "thrust washer" by GM....
its my understanding this engine is in the same family as the 153-L4, 194-L6, 230-L6 and 250-L6 engines, so maybe the bushing/thrust washer will be the same in these engines that are equipped with the EST distributor???
thanks for any help you can give
