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
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.

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

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.
