What spark plugs should I run in my 505ci wedge? It is an iron headed 11.5 compression street car. I am currently using Accel 134 plugs.

Accell is a good(but $$$) plug. Are you wanting to go to something cheaper or a different heat range?. what are your plugs showing now?

I am running a tunnel ram with 2 holley 750’s. They are coming out a little dark. I have been playing with the idle mixture screws and am having a hard time dialing the idle in. I was thinking about putting in a hotter plug to see if it would help the idle.

Harly if your plugs aren't fouled out(& it doesn't sound like they are) I would attack the carbs.
