What is your favorite Street/Strip plug for the inline 3.3L 200 ?

I am looking for a little hotter plug to run and wanted to see what experiences others have had finding a good Street/Strip plug for our little inlines.

NGK 7510 iridium tip plug.
If you have a decent ignition system like MSD gap at .045-.048"

Thanks for quick response Billy !!!!!

Why is this in the 240/300/4.9L forum?
