I know there is a adapter to run RB distributorin a B block ,But I have a old duel point distributor from a 383, That would like to install in a RB block. Maybe special made oil pump drive ? I am not looking for performance, I just like the looks of distributor and would like to put it in my 440 that I have in my 62 polar 500. Anyone know if there is such adaptor.

Nothing commercially available to do that swap. Only practical way to make it work is to change the shaft in the distributor to an RB shaft.

cut the shaft off of a spare dist & contact a competent welder (mig I believe). Ask him what needs to be done to keep it concentric as he welds (V block?). Wouldn't be the first time he's had to deal with that. Oughta be a piece of cake. I'm getting ready to do this with the 3/4" steering col shaft. He's gonna weld it together at the cut joint with a sleeve/collar already on it the slide it down over the welded joint then weld each end for a total of (3) welds as opposed to (1). going from power to 16:1 manual on the stock car

It's pretty easy to swap the shaft out. Why worry w/ welding it?

He'd basically have to find a dual point RB distributor as the donor, may as well just put that in.

Cut the shaft, use a coupler to adjust the length and run it, not a lot of stress there.

Don't be the exception.

Miracle! I agree with Supercuda.

There is ABSOLUTELUY NO NEED to do any more than splice the end of a shaft onto what you already have. May I suggest cutting a slot in the end of the extender for the tang to fit into? Then a single roll pin might be all you need. If there isn't enough room, a long collar with two roll pins would be sufficient.

The distributor takes very little power to turn.

Depending on the shafts' hardness, it may be necessary to have a machine shop do the drilling.

Correct , the description is wrong .

The only way do do it is to make an extension or find and RB shaft... good luck .

That adapter will let you use a 440 dist in a 383 but not the other way around.

Wrong again , there is no adapter like the one pictured because a 383 dist. needs a LONGER SHAFT , those adapters space the dist. off the block because of the 440 shaft .

The difference between the 2 you linked are because an MSD billet will not fit in one that is made to fit a stock dist.

This is off the wall but...318-440 shafts are very near the same length. work
Would there be a down side to using a 318 single point shaft? shruggy
I know the rotation is opposite...is the profile the same going each direction?. shruggy
With no picture of the distributor in question I can't picture exactly what the dual point reluctor looks like... runaway

Is the distributor like this one? realcrazy

There is 1/4" difference in the shaft length on each,440 on left,273/340 center and 383 on right.Also the 273/340 cam will put you two wires off on the cap.

Years ago I made the mistake of using a 383 B motor distributor in a 318 A motor, I could get it to start fine but it would retard the timing the higher I revved it shock RB and B distributors rotate counter clockwise, A motors are the opposite so if you used the 318 A motor shaft and advance mechanism it will probally do the same thing work shruggy
