Big block spark plugs

[Avalanche]

I am running champion plugs now In my 440. It's stock with a whiplash cam. I need to change the plugs, are there better plugs out there?
What are you big block guys running?
Gap ?

Thanks

All Mopars came O.E. with Champions. The spark plug was designed for this application. Are you having problems with your spark plugs or just want to try something new ? Get a new set of the factory Champions and then something else that you are curious about. That way you can always put the correct plug back in.

Yep, no need to reinvent the wheel. I run Champions and have them gapped a little longer with the addition of electronic ignition.

What gap are you running , I believe I have them at .35 now.

I've got mine gapped at .42.

I agree .042 -.045 works well with a high output coil & good wires
