I have a 71 240Z an this is not the OEM distributor to my knowledge. My car came with a D615-52 which is currently on the car (but recurved from www.advanceddistributors.com).

I have no idea what this came from. It was an ebay find that was just too inexpensive to pass up. I have ordered a new pertronix to put in it and new taylor wires to keep for another build I have in mind.

Which year, make model came with a D611-54.

Any idea?

The centrifugal (centripetal?) advance numbers should be stamped on the weights inside. A picture from the top of the insides would be interesting.

There is a spreadsheet out there on this forum somewhere with a listing of the distributor part numbers.

Edit #2 - the updated sheet n Post #19 has your second number. Looks like a 1973 240Z with a manual transmission. The weights and vacuum advance can be swapped between bodies though (as you now since you have a re-curved one), so nothing is certain.

I will be interested to see how this one compares to the one I am running. Thanks for that. I had forgotten about that post from a while back. I will see if I can get a picture of the weights stamped inside as soon as I can.
