And why  would you not want ported vacuum going to the distributor on a small 
block?  The small block engine doesn't work any different than a regular 
Corvair  engine, Or different than any engine that I know of and they all use 
ported  vacuum for the distributor except for the turbo.


You do want ported vacuum - just not at idle! Neither Chevy Small block or  
Corvairs are designed for vacuum advance at idle.  - Seth
