Valve timing specs for 2000 motors

[Godfrey DiGiorgi <ramarren@xxxxxxxxxxx>]

I'm curious about valve timing specifications for the A-R 2000 motors. I 
don't have a full listing and have been trying to assemble one. I have 
the two CarDisk collections for the '75-81 and '82-'89 series Spiders. I 
was able to find the following info so far:

- -----------------------------------------------------------
     Alfa Romeo 2000 USA engines - cam timing specs
- -----------------------------------------------------------

          Intake     Intake      Exhaust     Exhaust 
          Open       Close       Open        Close
          BTDC       ABDC        BBDC        ATDC     Notes
          -------------------------------------------------
1982-5    24* 34'    80* 34'     63* 54'     27* 54'  static, at revs +10 
degrees
1980-81   ????
1978-9    33* 54'    57* 54'     51* 14'     27* 14'
1976-7    21* 54'    69* 54'     63* 14'     15* 14'
1972-5    ????
- -----------------------------------------------------------
Somehow, the inclusion of minutes in the listing seems a bit of hubris... 
Doesn't the vernier in the cam drive allow 1/3 degree accuracy max?

The '82 has the VCT system on the intake cam -- I think this advances the 
cam 10 degrees at rpm above 1800 or so, and I believe the values above 
are the static ones from the '82-85 engine manuals which is why I put the 
note in there. If anyone has more exhaustive notes, particularly 
including the early '70s and european issue cars, I'd love to know what 
the differences are. 

So the question is, what cams would be usable in the '82 Bosch L-Jetronic 
motor and still meet the California emissions requirements? I believe the 
pistons going in will raise the compression ratio to about 10:1 and I 
know that will meet the CA cert without problems, I'm curious as to what 
more could be gotten from it with a cam swap.

Thanks for any info!

Godfrey
