From memory, about 10.6mm but don't have source/reference aside from puting a dial caliper to it.

No idea on the lift. I'd look for variations between lobes. Having said that, I don't know how much of a spread I'd be willing to accept. A lot of the answer would depend on what replacement cams cost.


But do you know the lift. If I can find this out then I will know for sure if my cams are worn

Thanks

264 deg seems to come to mind from way back. This, if I'm not mistaken, is the same duration as the SOHC cams.

'88 E-28 US M5 w/ wimpy 245 deg cams


I have been offered Schrick cams in the UK with the following spec

Duration 272 degree, 26,66,66,26
Valve lift 11.0 mm

They are said to be fairly hot accross the rev range.

I have tried to get origonal specs from BMW but with no luck whatsoever.

Does anyone know the specs for the origonal BMW cams for these engines or has anyone got 272 Schrick cams in there engines - how do they perform?

Cost is £529 for Schrick against £445 BMW

Many Thanks

Ian
