Im in the process of finishing my 340 build and would like to close off all engine openings to avoid dust or critters from entering my motor. I need spark plug selection advice.
My motor is a .040 over stock stroke 340. Aluminum heads, 242/246 solid flat cam, 11:1 compression and I will be going with the FiTech system.
I have always preferred Champion but I've been very pleased with the performance of NGK in recent builds (non mopar). What heat range plugs should I use given the build?
