I replaced my original dual vacuum distributor on my 55 272 with a 57 single vacuum distributor
the original had a place to oil the 57 oiler has a plastic plug
do I have to oil?
Are you the gentleman that had another member here pump up your 272 with earlier engine parts and a 1956 dual diaphragm LOM DIST?
What DUAL ADVANCE DIST was used to replace the LOM?
cvicky, here's the reason why...I don't know if it has already been said, but the engine will not perform correctly by dropping in a '57 and later distributor with mechanical advance unless you ALSO replace the original loadomatic carburetor with a '57 or later style carb.

Yes it will work, but unless the carb is modified neither fitting will supply the right vacuum level for a '57+ distributor.it seems to be working with my 4 barrel holley t pot and three speed manual trans
I m on the lower vacuum and pluged the upper vacuum

Back in reply # 7 there is a link to an article from Eaton Balancing with the step-by-step How-To...how can I modify t pot to work with 57 distributor
ive tried to get dual vacuum distributor woth no luck
any ideas
It may be the wrong cap for the distributor??? I believe the caps for '56 and older are slightly smaller than the '57 and newer caps, they aren't the same size.oh and oil pump shaft to distributor was to long rotar was hitting top of cap ...
Please look closer at these two pictures. The distributor with the double sided vacuum canister is only '56.yes I compared pics to my 57 distributor and t pot carb they are the same
someone earlier was saying dual vacuum was only in 56
my car is defenatly a 55 Fairlane the letters on the block indicate 272 even though the paperwork I got from estate says 292 everything else cheques out
FYI, the distributor in your first photo is a '56 specific version, with a points conversion kit installed.my dual vacuum distributor has 2 springs and a large rotar FTD12127-B2 634 came on my 55 Fairlane
my second distributor single canister with bent arm and silver plates inside small rotar markings are worn off will work with adjustments on T pot
