Plug selection - 10/17/13 12:35 PM

Hey guys, I need to decide on plugs for my build. I have a 440 that's .030 over running 10.6-1 compression with the 452 MP aluminum heads and a 480/490 lift cam ground to dwayne porter specs. Also running HP manifolds. Nothing fancy just trying to bump power a little for an auto and a/c car. What plugs do you guys recommend????
Thanks in advance

I usually use Autolite AR3910 for Edelbrock and MP aluminum heads in that range.

Plugs can make a difference. But what works well for me maybe garbage for you. Buy several sets, and experiment. When you hit the happy spot you'll feel it and see it on your time slip. i'm using NGK BP5S right now. Spark plugs Take a look here for the selection possible.
