what distributor????
I HAVE A 1956 Fairlane with a Tbird 312 CI V8 and it came to me with an Edelbrock 4bbl. Its very anemic and I was told I needed to use a 1957 distributor. Why and should I? Thanks from balmy northern Maine.

Re: what distributor????
('54, '55 and) '56 distributors advance the ignition timing based on vacuum, only.
The vacuum pressure needed by a '56 dual timing advance canister is one-year-only, not the same as earlier or later. Without a '56 teapot carburetor and its matching vacuum port, an existing '56 distributor cannot advance the timing properly. It can/will run sluggish and may tend to overheat. The '57 + distributors have mechanical timing advance in addition to the vacuum function. A '57 or newer carburetor like you have has a vacuum fitting with a pressure level that matches a '57 or newer distributor. https://www.ctci.org/gilsgarage/Vacu...Mechanisms.php https://www.ctci.org/gilsgarage/57distributor.php .

Thank you. I'll see if I can find a 57 dizzy out there somewhere. Jim in frozen Orrington, Maine.

Re: what distributor????
I'm assuming the engine has the '56 small bolt pattern ECZ-A intake manifold with an adapter/spacer to mount the Edelbrock 4bbl carb.
Almost any '57 thru '64 y-block dist should work. There are some internal differences in distributor construction: '57-'59 and then '60+, mostly the mounting of the pivot plate for the points and the shape of the arm from the advance diaphragm. A '57+ dist will have a notch to index the rotor and uses a different cap & rotor than the earlier ones. Lateral play in the shaft bushings and a bad diaphragm in the vacuum canister are two things to check for in a used dist. . Last edited by dmsfrr; 01-20-2018 at 01:10 AM. |

Ted Eaton has some excellent articles on his website that explain carb mods should you ever go with a mid 50s carburetor

How long have you had the car? Have you checked the points, timing, intake manifold vacuum, done a compression test, adjusted the valves... ?

Re: what distributor????
Check the timing, Y- Blocks like more timing than is listed in the manuals. I have between 10-12 on the crank and 34 total

Re: what distributor????
There’s been some complaints lately that some “y block distributors” aren’t. They’re a little short. Look close before installing.

Re: what distributor????
I was gonna mention that - recently complaints have surfaced. Y Block cores must be getting scarce again. 30-2808 is the Cardone #, but they are apparently using something else for cores on their rebuilds? Not sure what is going on. Dimension between mounting boss and gear is critical.

Re: what distributor????
I bought one of the Cardone Distributors a couple of years ago. it was a little short, and I did not like the way the oil pump drive shaft engaged. It was a little short and did not sit deep enough. I ended up not using it , because I did not want to take the chance of an oil pump failure due to a cheap dist. that would ruin a new engine. I am going to end up using an MSD. the eng. has not yet been installed in my avatar.
