Spark plug Recommendation for Pro1 215
I am in the final stages of building my Iron eagle based 427 sbc and I am looking for recommendations on spark plug #'s. It is a Street/Strip deal with 11-1 compression 672 lift roller cam, CNC'd old style Pro1 heads, t&d Shaft mount rockers, Eagle rotating assembly, CNC'd 2975 Victor Jr., HVH super sucker, Aed 850 Ho Carb. I have always been partial to NGK plugs, but any recommendations would be appreciated.
