Default What spark plug for a 355 inch in my wellcraft
Hey guys, I replaced the tired 200hp 305 with a 355 inch aluminum headed motor I built. Is there a consensus on which plug to start with? Motor is as follows

355 inch
9.4:1
Ported edelbrock rpm heads
custom ground hydraulic flat cam
performer rpm intake
600 edelbrock carb
