There is an HEI set up on EBAY which states:
YOU ARE BIDDING ON AN H.E.I. DISTRIBUTOR NUMBER 1110715 FROM A '79 CHEVY 250 SIX INLINE SIX. IT IS IN VERY NICE, COMPLETE CONDITION. THE CENTRIFUGAL ADVANCE IS NOT WORN OUT OR SLOPPY, AND THE VACUUM ADVANCE WORKS FINE. IT'S EASY TO PUT ONE OF THESE IN A 1937-62 CHEVY OR 1939-59 GMC SIX; JUST GRIND OR MACHINE OFF THE LOCATING COLLAR ON THE ALUMINUM HOUSING AND USE A STOCK CLAMP-ON LOCKING DEVICE FROM A STOCK 216-235 DISTRIBUTOR.
Is that all thats required to convert this fairly common boneyard part to make a 235/261 run better and get better gas mileage?
