Hi
I have a pair of non standard (i think) cams from my ph1 6 engine,
that met its maker in the last session at snetterton.... Pilot error

I am transferring them to my new engine and would like to know
how best to set them up timing wise.

inlet is 11.1mm of lift over base
exhaust is 11.1mm of lift over base

not sure on duration values

I will post pics of the cams and markings.
Cheers for any help

That seems a large lift! The cams should have their id stamped in the end like these below....
Not a very clear picture but you get what I'm saying.....Thumbs up

I will double check, in the mean time do you know what the base diameter is for standard cams?
