camshaft Identification
Hi Just stripping the engine that came with my part build.
It has obviously been rebuilt and never run but I dont have any history of it.
The head has been ported and I am wondering if the cam is non standard
On the back end there are some markings
M2 space then a 2 turned 90 deg left then 70
opposite this there in a faint number S12-8
And in another point there is a UK stamped.
Any Ideas ?
I have looked on Burtons site and cannot see anything that comes close.
Cheers
RD

I'll try again with a better camera but they dont show up very well.
If camera fails I will draw them out and photo that.

Been on the piper site and yes it looks like it's a piper fast road cam with 270 deg duration.

You can go up a cam or two easily, the 285 is very good al-rounder, you could go to 300 as long as you have higher compression ratio to make the cam
