From the specs you have given the cam will have a nominal timing around 50:80 inlet and 80:50 exhaust at 0 lift.

Its hard to measure cam timing exactly with out a cam doctor but that would be close.

For your exhaust calc you would use 80 degrees before Bottom Dead Centre (BDC) for the calc on page 115.

Thats a big cam for a turbo engine
Planning something special are we?????
