Would this dual point be a good distributor to have rebuilt and run?

It looks like a late 60's dual point is there still a tag on it?

No sir just the numbers stamped on the bottom of it

 

[HALIFAXHOPS]

Thats just a casting number, can be anything from a 273-440. See if you can figure out which one then it is a crap shoot to what the curve is without taking it apart and measuring the camplate etc. looks like a B/RB by the position of the Vac advance.

Measure the shaft from the base to the end! That will tell if it's an RB,B Block, or a small block!

My 67 R/T had one of those from the factory. They are a real pain in the backside to set and adjust. After messing with it for years, and having it re-bushed at the machine shop, I finally did the best thing ever for the car's ignition. Took it out and installed a Mopar Performance Electronic Ignition kit with a new distributor.

Look at the rotation of the advance.

The newer electronic versions are easier to deal with and stay constant compared to any points stuff. Just say'n.

Send to Joe's distributor service in Ohio a good solid part for sure

BTW a good dual point distributer can perform very well. They just take maintenance.

IMO....I concur with Halifaxhops' a observation and add the following comment.....later years, 1968 and later, use a O-ring to seal the distributor body to the block, which this unit has. Earlier distributors used a thin raised bead copper crush washer to seal to the block.....very ineffective.
