I heard or read somewhere that the shaft in the 1111480 distributor was different than other GM distributors. Is this true? I found a distributor but it is thoroughly trashed from corrosion and pitting. Must of sat in water for many years. Anybody know where you can get a replacement? How about the correct vacuum canister. I have a Crane adjustable I plan on using if there aren't any around. Any suggestions on what I can do to get a standard none 302 GM distributor to work?Looking to keep it all stock looking as well.

If I remember correctly the only difference was the lobes had a more gentle point opening ramps to reduce point float at high RPM.

Also the 302 points have their on P/N. The points on the 302 cars have stiffer springs on the points to help prevent points from floating at high rpm.

I was of the understanding the curve was different as well. I don't know that for a fact though. Maybe John Z will drop in!!

The 1111480 distributor used (only) in the DZ application has a unique long-slot advance cam and much closer tolerances on the (hardened) shaft and housing bushings. If the one you have is badly corroded, try Jerry MacNeish at(410)781-0418 for a quote on a rebuild, or T.I. Specialties in Florida ( ). I haven't seen a decent genuine 480 distributor go for less than $450 recently (even 480's are being re-stamped now that they are so valuable). If numbers are important to you, I'd try and save it. Jerry's doing my 480 right now.

The advance cam is part of the shaft and is stamped 532 (32 degrees advance). The 532 cam is also used in couple other 69 distributors.
