Too Hot

-
That’s my set-up. I have a shroud, correct for my ‘69 rad top tank. I have springs in the bottom and top hose, I still confirmed they aren’t collapsing. I checked air movement through the radiator and it pulls more air with increased RPM. I am assuming it’s moving coolant as the bottom hose becomes very warm. The fan is facing the correct way. The tubes look fine, nothing spaced too close or touching and the fins are all in good condition. I couldn’t reach Bob at Glen Ray but will try again on Monday.

I’m still tuning the six pack, learning what it likes. AF at cruise (55mph@2600 RPM) is around 12.7:1. Goes very lean at WOT before outers start to add fuel, trying to remedy that.
Plugs are sooty, dry, not oily. Plugs are Champion RC14YC, oil is Amsoil ZRod 10W30 full synthetic. Fuel is 90 octane at the pump.
