[R500_WKD]

I posted this in the 993 forum but didn't get any replies so reposting here if anyone can help.

I'm in the process of selecting a new cam to increase torque in the 4000-6000rpm region whilst maintaining hydraulic lifters. I have cam cards for the WebCam RS Euro, Dougherty RS and RS2, but I can't find anywhere any reliable numbers for the standard factory cam at .050" so I can run a comparison.

Can anyone help with IO/IC/EO/EC, lift and lobe centres for the factory cams?

Thanks for the help.
