The cam degree calculator I mentioned earlier also gives the overlap based on the info entered.
Alot of the GM cams can be hard to figure, GM rarely provides the true ICL of their cams & alot of the published durations are listed in true actual seat to seat vs @ .004, .006, etc.
Keeping the TBI computer happy means retaining as much vacum as you can & small overlap.
