496 fouling plugs
OK, am going crazy!!!! got a built 496 stroked engine runs great for about 6 miles or about 10 minutes of running. The plugs are completely carbon fouled. I went from a Holley 850 double pumper to a 750double pumper then to Edelbrock Easy Street EFI same thing. Change the plugs runs great then they foul Timing is at 16 bt I have been told to go to 12deg and some say 20deg am going nuts I just want to drive my car I have talked to Edelbrock and blue print engines still same thing. am at about 9200ft about sea level. running HEI with a MSD mod.
You're welcome Mike, glad it worked out for you. Roger, it's taken a few years but my inventory of excess parts has shrunk a fair bit from 1 1/2 garage stalls to about an eight by eight space. ...
