ok, i have an 86 mustang, i am doing a 4 cylinder to v8 swap, the v8 i built has many modifications, it is bored 40 over, 11.3 to 1 compression, 292/510/510 cam, edelbrock intake and carb, forged steel crank, forged speed pro pistons, msd ignition, 58cc heads, high performance oil pump, headers. etc.... what kind of spark plugs should i use that will go good with this setup?

 

autolite's or ngk's will work fine.

 

don't expect anyone to give you a good recommendation.... My crystal ball can't tell me what BRAND heads you have...
