Lucas 25D4 40872 distributor users?

[Ian Williams]

To clarify, I used the mechanical part of a 25D4 in a no vacuum Lucas body 23D I think from memory and I would have also made a few mods to the advance curve. I used this set up for many years successful racing and on more than one rolling road my car produced around 36 to 38bhp. Perhaps I could have done as well on circuit racing with a locked distributor but my special was also run on the road some of the time and I wanted to retain some flexibility in the engine. All I can say is it worked for me, and I probably ran the quickest non blown car that was raced here in NZ, I certainly never came up against a faster car other than a blown special that simply out dragged me on the straights.
