I bought a Prestolite distributor unseen from a guy who restored this car and had it left over. He said it was a Hemi Cuda and the owner wanted electronic ignition instead of the dual points, so the restoration guy kept the distributor. The only problem is the tag has been broken off. The distributor is in real nice shape, any way to tell what it's from without the tag?

No, with no tag, there's no way for a positive ID. It's just another dual point, but those aren't exactly cheap these days even without a tag in that condition. The vacuum diaphram does look correct for 1970. Does the cap have "Made in the USA" molded into the top?

The cap does have the "Made in USA", it's pretty nice, doesn't look too worn, but a little chewed up on the top of one of the towers. It would be under the plug wire boot though. It needs some cleaning though.

That's a correct cap. All in all it's probably a Hemi distributor, looks the part but it could just as easily be a 440 unit, as I said, no tag, no pos id. Reproduction tags are available but be forwarned, there isn't one out there that will pass as the real thing, they all have small flaws that make them recognizable as such.

Look at the arm on the vacuum advance and see what the stamped number is.

Also check for numbers stamped on the centrifugal advance shaft.

Thanks for the info. I originally wanted it for the shaft to repair another distributor I have, but I think it's too nice to strip for parts.

I checked out Paramounts site, I would love to have one of those Sun distributor machines they have. Probably wouldn't get much use, but would look cool in the garage. Kind of an expensive piece of garage art though.

At least it is a 70-71 BB distributor.

If you decide to remove the shaft, look on the bottom plate for a stamped number. There will also be a letter stamped on the top plate, but I don't know if it is relevant.

There is an "8" stamped on the vacuum advance arm. Do you know which distributors got which can?

I don't have one of those distributors, so I can't be of much help. Maybe one of the AAR or T/A guys can answer your question.

Funny enough, I also have a dual point distributor missing the tag that I bought as a '70 440 6bbl part. It wasn't as nice as the one above, so I completely disassembled it, cleaned it up, glassbeaded and painted the housing, etc. I just checked the vacuum advance arm and it is stamped 11 and the wire lead is the long 6bbl type, so I guess it is a real V-code distributor. Snoopy, what will be stamped under the advance mechanism if it is a 6bbl distributor? I already assembled mine, but I will pull it back apart to find out

'70 Super Bee 440 6 pack 4-spd 4.10 Dana N96 EB5
‘70 Super Bee 440 6 pack 4-spd 3.54 Dana FC7
‘70 ‘Cuda 440+6bbl 4-spd 3.54 Dana N96 EB5 V1W

I don't know, I only have a manual 70 Hemi shaft on hand for reference.

Other than the number on the tag, is there a difference between a distributor from an auto car as opposed to a manual car?

Hemi Distributors.
Prior to 70, auto and manual used the same distributor. In 70 & 71 a different distributor was used for manual and auto transmission.
The difference is shown in the chart below.
From the 70-71 Factory Parts Book.
2875987 - 70 Hemi Manual trans.
2875989 - 70 Hemi Auto trans.

Thanks for posting the chart, that is interesting. It looks like the only way to tell the difference between an auto and manual trans distributor would be to take it apart and see what is stamped on the plate attached to the shaft.

The only problem with that being is the numbers are Prestolite numbers not Chrysler.

Maybe this will explain the differences?
