1947 Ford v8
I have a 1947 Ford car with a v8. I bought a 12 volt billet distributor for it, which will bolt on fine. But the original distributor has a hole on the back of it. The new distributor does not have a hole nor does it cover the hole that is in the block. I assume the hole is for oil. Has anybody ran into this problem? Can i plug the hole? Any suggestions? Thanks in advance

Re: 1947 Ford v8
vacuum fitting hole, does your original mount/adapter have the vacuum line from it to the manifold/carb?

Re: 1947 Ford v8
Your new billet distributor most likely does not use the vacuum brake sit up the original used. I would guess it is centrifugal advance only.

"unsure12" - How familiar are you with the operation of the original distributor that came on these engines from the factory? If you don't understand how those worked, I would imagine that the information given (though good), may be gibberish to you.

Re: 1947 Ford v8
Maybe it would help if you explained it. The hole is connected to a vacuum source originally. If it still is, you need to plug that supply. Your new distributor does not need it.

Re: 1947 Ford v8
Don t forget, the vac line and its part in the original distributor was there for a reason.

Re: 1947 Ford v8
The vacuum for the 8ba dizzy it piped to the carb. Am I missing something here? Run points and mechanical weights, if you have to have a vacuum to the dizzy on a 8ba well.

Re: 1947 Ford v8
What distributor did you buy to replace the original. the original in proper working condidion is a very good distributor and the advance curve needs vacuum as well as RPM to give the proper advance.

Re: 1947 Ford v8
The 1947 was still running the 59 series engine in cars & trucks. The 8BA came along in 1948 for trucks the 49 for cars.
The rabbit ear or crab type distributors still have value. If you don't want to keep it then someone likely will want it. They are a decent distributor since they have both centrifugal advance and the vacuum brake for load spark control. Centrifugal distributors don't have load control for better mileage at cruise speed. |
