    As the lift on shaft is bit higher and shape nearly the same i think that will be not much difference - only one big change is angle between lobs - J i wide - that new one narrow.

    Who knows what is the angle between rocker arms in and ex?

      So question number TWO - do you (or some-one) knows which engines has camshaft with big bearings ? Maybe that will show up what this camshaft is....

          So it can not be something really bad as 90hp 306 version. Maybe it's S1 as it has different torque spec to S2 so maybe that's the case.

          So let see what it will do as i'm back to ori soft for safety.

          Have to start to tweek soft again. Do you guys have experience how far with ignition advance i should go with my mods ? (Head skimmed 1mm and head gasket 1mm thick instead of 1.37 ori)
