[V8Vairs] Fw: Backfire through the carb...

[Secular]

  Hi:

  Eureka !!!  The culprit was a BROKEN spark plug ! It was split in half 
  barely attached to the combustion chamber end :)

  The brand? --- AC spark plug R44F !

  Hi:

  327 SBC on my V8 vair. 
  Electronic ignition
  Headers

  I have a brand-new Edelbrock 750 CFM installed recently. The car idles perfectly @ 950 RPM. 
  However, it backfires through the carb while driving. 

  Timing is set @ 8 degrees. 

  I've checked the firing order also. Distributor cap is new so are the plugs. 

  A friend told me that backfire through the carb is mainly due to a "lean mixture" !
  Is this true?

  Regards,
