Spark plug advice
Obviously plug preferences are like asking what oil is best to use, but just for kicks I’ll tell you I run NGK in everything.
My 9.5 compression Magnum has had NGK GR5’s set at .050 in it for 5 years or more and they have been flawless.
(Thinking to put new ones in anyway):D
I am running a Holley Street Avenger 770 that performs great in all ranges, and I know for fact a 750 isn’t overkill on a 408.
In fact my own opinion is that a 408 could use all of an 850.
BTW, one of our local Mopars4us group picked up one of your K members, A arms and power rack and pinion setup.
Impressive stuff.
