Vacuum cannister for a 1111024 distributor
Does anyone know where I can find the right vacuum cannister for a '64 300HP/327? I need the right one for a 1111024 (300HP distributor) or a 1111022. Both start moving the plunger at 8Hg and end at 16Hg (8deg.@16Hg) I was experiencing detonation under light acceleration (1400-2200RPM) using one for an L79 engine that started the plunger at 5Hg. I found an old (very old) cannister on a old rusty 1111016 ('64 300HP/327 Impala) that starts the plunger @8Hg and ends at 8deg@16(same as Corvette) that still works and doesn't leak ...yet and the engine performs as advertised with no detonation or stumbles etc. but I want to replace it before it fails ....and they all do in time since they are 50 years old. The over the counter replacement cannisters are too 'generic' for me and when I test them they seem to start moving the plunger anywhere from 9 -12HG and have no bushing like the original to limit advance. Specs call for 7-9Hg to start the plunger with a max advance of 8deg.@16HG and that works.
If anyone can point me to a source, I would appreciate it.
Thanks,
Bob

The VC-1802 (stamped B22) or the VC-680 (stamped B1) or the VC-171 all have the same spec - start @ 8"Hg., 16* @ 16" Hg.

Thanks for that, John. Do you have a suggestion where to find it? Advance (no pun intended), Autozone, Napa? As you are aware of, most of the folks behind parts counters now are 'clerks' and now real parts people. .....and do you happen to know if these cannisters have the limiting bushing or is the bushing still necessary?
Thanks

Thanks. It appears that the ACDELCO C1382 (stamped B1) from RockAuto may be the one. ...if the specs are as you stated since I don't know where to check the specs on this piece without already having it. Assuming that it does start the plunger t 8Hg, do you know if I should be concerned about the lack of the limiting bushing?
