| I have a theory.
I have an 82, 280. It has a new crate engine, new radiator, new clutch fan, all new engine stuff. It cools great at idle. It gets warm at speed. (approx 210) Let it idle again and its down to 170.
I know it's making more residual heat at speed so it has to dump more heat. But there is the cooling fan shroud that looks to me like it is blocking the natural ram air at speed thereby making the engine run hot.
Take off shroud. More air at speed. Better cooling.
Anyone?
