E3 Spark plugs do work

Hmmm. I have a 600 HP small block going back on the dyno here real soon. We are using the 5672-8 plugs in it right now. I just got my monthly paycheck from Donald and I think I can spring for some E3's.


I'd love to see the results too.


Can you give a few details on the engine. Street deal? Strip only? What CR?


Thanks.
