[V8Vairs] Backfire through the carb...

[Secular]

  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,


  Tony I.
