What Spark Plug do I need to run?
I was wondering if someone could recommend a spark plug for my engine. It a 355 with 10.5 compression out of the box trick flow heads and it's carbed. I am running it N/A. I also have a MSD 6AL box. Just wondering what plug would be the best. If you need any more spec just let me know. Thanks

I have several more questions that should help us make an educated guess at the dynamic compression of the engine:
What duration cam? LSA?
What peak RPM?
What is the head chamber volume (cc)?
What type of ignition system are you planning?
Each of the three factors will affect dynamic compression. The last answer will help decide what kind of spark energy will be available.
I would recommend copper cored Champions, of course, but the rest of the information will help determine heat range and gap.
