Identifying cams

[Wobba]

I've got some OEM cams here but I've been told different things and am not sure if they are Willy or Meg. I think they are Meg as they look like they may have different marking to the other Willy cams I have in my spare cylinder head, but how do I tell?

As the meg runs wasted spark I would assume that megane cams wouldn't have the notch on the exhaust cam for the dizzy?

[Wobba]

Good thought. There is one notch on the end of one.

Yea I did wonder. Any of these numbers or markings mean anything?

the cams do have notch 100%. iirc the cams are the same as willie ones specs wise... ore am i wrong?

when manufacturers remove the dizzy they dont normally go to the expense of changing the cam when it will work fine as it is.

Meg F7R ones are a tad milder I hear.

williams cams have a yellow paint stripe round them.

Wobba, measure the cam lift:

F7P: in 9.17mm
F7P: ex 8.56mm

F7R Williams: in 9.83mm
F7R Williams: ex 9.07mm

F7R Megane 2.0 in 9.09mm
F7R Mgane 2.0 ex 8.71mm

if I'm right.
