I have a couple of WRC cams from 92/93 engine. They are marked with 9094773 and 9094774, these are inlet & exhaust respectively. However I would like to know the specs of these, i.e. lift, duration etc.

I want to see how these compare to BD15/16/+. I realise that these are probably design to work in conjunction with 34/38mm restrictor, WRC turbo & more.

Here's hoping someone out there can help.

Cheers
Graham
