I would look at reducing the power steering pump flow. 7 Degrees is plenty for the setup.

I have a R&P in my 78 and added this.

While I believe it is still to light of steering (compared to my 2010 C6 GS), Many companies make these, all you need to find is the correct setup for the hoses. Mine required AN6 fittings, but you can get them for the factory PS hose setup. I believe the default C3 PS flow is 2 GPM and could be as high as 3 (rebuilt PS pump using the wrong setup for the corvette).

Read these tech notes.

Borgenson kit / shim kit may not work. I went with a flow restrictor option.
