1966 distributor vacuum

[Don O'Grady]

Can anyone tell me if the vacuum canister for a 1966 distributor 350 hp is the same as for a 300 hp. I think mine might be for a 300 hp and don't know if I need to change it. Any help would be appreciated

Well I still have the Delco book out from the answer below. Maybe I should keep it at hand.

1966 300 hp dist = 1111153 vacuum can is 1115355
1966 350 hp dist = 1111156 vacuum can is 1116236
1966 350 hp dist TI = 1111157 vacuum can is 1116236

One would have to look at original cars, but I would expect the 350 vacuum to have 236 stamped in it, and the 300 to have 355 stamped in it. Don't spend all the milk money on a vacuum unit until you hear from some folks with original cars. It doesn't happen often, but I have seen cases where what is "in the book" is not what was put on the cars.

Hi! Type 1116236 in the archive file and you should find the information you wanted.

The "236" is the correct vacuum can for the '66 L-79 (0*@4", 16*@8"), but don't spend big bucks for a NOS version. The NAPA/Echlin VC 1810 is functionally equivalent, although it is stamped "B28" on the bracket rather that "236-16" as on a NOS Delco.

At Monterey last summer I asked the 63-64 Team Leader about "incorrect" vacuum cans and he said in so many words - if it's not in the book we don't deduct.

There is nothing about the vacuum can numbers in the current 63-64 JG, but I don't know if anything is said in the '66 JG.

The NAPA/Echlin cans have the same outside geometry - looks just like the original Delco can - just the different ID number stamped on the bracket and it's my understanding that if you buy a current "Delco" 236 vacuum can, you get the same one stamped "B28" as Delco is now apparently just purchases them from Dana Controls.
