Steering effort for manual 16:1 - should it be this high?

Cost, weight, parasitic drag aside, The thought of installing power steering again gives me pause. The OEM power steering box was a monstrosity. I had to unbolt the header and lift the motor to get it out...and it still took a long time to free it from the engine bay. LOL. Getting it back in would almost certainly be worse.

How was the install on the Firmfeel box? It's a different casting, correct?

FrimFeel is the stock box, just rebuilt better than stock and different firmness installed, they have 3 stages. My dad has a Stage 1 in his Coronet too, its nice for a bigger, heavier car with a 440 and a 4 speed.

I did have header issues with my Doug's not wanting to clear the factory coupler. I ended up with a Flaming River tilt and its smaller universal to clear. The Borgensen box is smaller and a faster ratio that stock. I think 14:1. Might be worth looking into.
