Spark Plug for the small block motor

[dodge freak]

I have always used Accel U Grove plugs 116 and 114 but would like to try NGK. The guy at Summit racing was no help, not sure why they can't get better help there. The big block post was good so I thought I would ask about the small block. I know its 14mm and the reach is .750 but what # is a good NGK non-resistor plug. Any other brands would be fine too. Thanks guys.

Anybody know?? Ok the 400-440 are better motors but the 340-360 aren't that bad once you rev them up. I would have thought somebody would know so I am bumping this up.

I run Champion platinum's # 2405.

They're the platinum replacement for RC12YC4's gaped to .038.
They're a little shorter than RN type plugs and use a 5/8ths hex which gives you a little more room if you have headers.

I am not a fan of the Jap NGK plugs , they foul & quit firing very easily , i would use Champs
