Short Shaft vs. Long Shaft
What is the advantage of using a long shaft vs. a two piece short shaft with your distributer?

Re: Short Shaft vs. Long Shaft
I would think one less connection to get "slop" in. Anybody else?

Re: Short Shaft vs. Long Shaft
more maintenance, I guess. I have not seen a double shaft in the model A...

Re: Short Shaft vs. Long Shaft
More wear on your distributor bushings? That's why I thought the two piece was better.

Re: Short Shaft vs. Long Shaft
I am not aware of any advantage of the long shaft over the short, unless you have a NOS block, head gasket, head, etc. to use it in.
About every distributor I ever saw with a long shaft (and good distributor bushings) wobbled some in the head and if left alone wallowed out the hole and wore the distributor base. The rest had worn out bushings. |

Re: Short Shaft vs. Long Shaft
IF there was an advantage, Henry would have made a long shaft AND saved $

Re: Short Shaft vs. Long Shaft
In rebuilding distributors have found the one piece shaft doesn't run true, wobble, causing point openings to vary. Suggest you use the two piece original set up.

Re: Short Shaft vs. Long Shaft
The two piece shaft allows some movement and releaves pressure on the bushings. We run two piece shafts in all the Model A Times project cars.

Re: Short Shaft vs. Long Shaft
Remember that head and block were machined separately, and that there isn't anything to register the head location more precisely than the studs anyway. Concentricity is unlikely, within available near-nothing clearance of a good shaft and bushings. Get new bushings and a 2-piece shaft set for that distributor!

Re: Short Shaft vs. Long Shaft
IF you have the original ignition cable, it is easier to remove the distributor from the engine with the short shaft. Having the two piece shaft assy does eliminate the potential wobble of the distributor shaft/casing because of mis-alignment.

Re: Short Shaft vs. Long Shaft
I had to file the joint between my 2 shafts to make them fit, which means that slop was minimized. I haven't thought it through if the single shaft could have it, but the drilling in the upper shaft allows dizzy oiling.
