Hey guys,
Wanted to see if I could get some opinions on my spark plugs I pulled out to check.
Appears to be a nice tan/brown to me on one side with some oil deposits on the other side.
If anyone sees anything im missing, please feel free to educate me. Im still learning here.
Plugs were pulled from cylinder #1 and #2, im using NGK XR4 #5858.
Was concerned it could be too hot of a plug? Running 91 octane at 32* all in.
No noise, just checking with you guys.
Approximately 500ish miles on them.
The engine is a factory ‘68 440HP, everything still appears to be original.
HEI distributor on it when I bought it.
