We used to use Champion, comparable to a Harley plug. That was in the 70s, so they might not do that anymore. It's worth checking out.

I bet the MoCo uses the cheapest bulk plugs they can find. I just installed NGK iridiums in my switchback, they have a sharp pointed tip unlike the cylindrical reg. plugs so don't pry on the tip to gap it. A slight improvement in the butt after install, hey the're just spark plugs.

Champion, makes the plugs for HD, with the HD logo on them. So, if you buy a regular Champion plug, your buying the HD plug minus the logo and the extra money for the logo.

I just use Harley plugs..always seem fine to me. It's been proven a spark plug will not make a difference in HP or Torque

I used to use the Champion RA6HC, which is the Harley plug without the Harley logo or price. I switched to the NGK DCPR7E several years ago.
