Cam Specs

[bruce plecan]

The cam is a Competition Cam part no.12-211-2
   The specs are
              open           close
          in  28 BTDC        61 ABDC
          ex  69 BBDC        21 ATDC    
   270d @.006
   valve lift .470"  duration @ .050 224d  lobe seperation 110d
Several comments received were that it isn't that large of cam,
yes, but when running large injectors (2@ 90#/hr), then idle
quality can suffer, and the manifold in use is the cross-fire
which has to have the largest wetted area ever thought of for a
small block.  Might add that the mid 13's it runs are done with
ease.  When chip writting I tried initial timings from 6d ATDC to
22d BTDC, and more fueling points than you can imagine.
