What Cam is fo me?

Need to know the current compression ratio before selecting a cam, coz you could be wasting a cam or an engine.
If it has 10:1 CR, a cam around the 30/70-35/75, 0.500"-0.525" lift mark, with 2* advance on the cam, run on 98RON, with 14* initial ignition timing, and recurved dizzy with HEI....be all sweet.......but it depends on how far you want to go.
