Hi Jukka,
Well, we have the data for the DB605A but, only some of the DB605DB/DC detail in genuine document. As you will know, the Nockenwelle is different between the DB605A and the D series engines with the forward scavenge pumps. However, here is some of the valve timing for the DB605A: Overlap 106*, Inlet Duration 306*, Cam timing, Exhaust opening 67*BBDC. All timings are taken at roller/cam contact with correct valve clearance set. The DB605DB/DC has the same cam timing setting but, no other details genuinely known. Cheers

SM
