Not Ranked
Plugs:
I have now ran Denso- equivalen for NGK 7- grade plugs. Very pleased.
Bought in a set of NGK 8- grade plugs. Are they too cold? Anyone else running grade 8 (NGK scale)?
These are non P- protruding type. P- type is listed for the small block. So, will this have a lot of influence? (Maybe this will give a greater amount of burnt feul/air? Who knows? I fear the opposit will happen.)
