BLOWN85

Was wondering what plugs you guys are running with blower motors? I am in the process of putting a weiand 256 blower on my hp 500 carb motor and am trying to find out what heat range of plug you guys are running. going to run between 5-7#s of boost on pump fuel (93).

I like NGK R5672-A10 in my blown gas engines. Have also had decent luck with mild blower motors using Autolite 3924 & 3934 just my .02 though.
