Fouled Plugs (2 out of 8)?
I have a fresh 427 center oiler (stroked to 454) with aprox. 1,200 miles on it. It has ported and polished Edelbrock heads and intake. The engine runs fantastic, but fowls plugs number 2 and 6 about every 400 miles. This is a rich fowl, not oil. All of the other plugs are perfectly colored. Did a compression test, all cylinders within 10 psi. No blue or black smoke out of either exhaust pipe. Tried a different carb., same sh*t. My friend says it is due to the dual plane intake, but I don't believe him. 2 Spark plugs every 400 miles is very cheap, but I would like to understand what is going on. Any ideas what is happening, or tests that I could do would be greatly appreciated.
