Hey guys I have a 505" six pack motor... took it on a long run today... 120 miles, and now cyl's 1 & 4 have rich fouled plugs(black soot). All the other cyl's plugs are tannish brown color... What gives??? How can just those two plugs foul like that?

3 things come to mind... too cold of plugs... too fat on the fuel and a poorly flowing intake(the runners arent balanced)

If I was too fat on the fuel wouldn't I have more than 2 fouled plugs????? I can understand the runner issue??? I am running a NGK BKR6E plug...

Since all of them are a tad fat(tan color) you could
jet down or put in a hotter plug... or put in a hotter
plug in those 2 cyl(it will work but not my first
choice)
