Anyone have spark advance data for Piper camshafts?


Freshman Member
I have been in contact with Piper about an NOS camshaft I have, an HR270/2. The end is marked M2 270. It is a Piper alternative to the much maligned BMC 731 camshaft. The Piper folks have been very helpful and responsive, but when I asked about spark advance setting for this camshaft they said one of their newbie employees had accidentally thrown this information away some years earlier, and if I found it they wanted a copy!

So, does anyone have any information on spark advance settings for Piper cams in BMC A engines?
