Despite the lead stains / deposits, I thought they were a little lean.
My engine builder swears by the NGK's. He kinda shakes his head on a restoration engine and I install AC's
I finally installed the ZL1 fuel pump yesterday. I must admit, Chuck got my attention when he burned down his 496. Not digging the fitment of the fuel line as it's right next to the lower hose. I'm thinking I need to research some period fuel line configurations. Also giving credit to Chuck, I feel inspired to add a nice matching Sun blue line fuel pressure gauge.
You guys have any neat pics or ideas? I've see more than a few Motion installs that have nothing more that rubber line after the pump. That is not an option for me.
