IM pretty sure its 35 psi. Thats what it says on my 86. I usually run lower than that for city driving. Too many potholes, bumps, etc.

I believe there is a TSB from Chevy regarding customer complaints in reference to a bumpy ride. It says to lower the tires air pressure. I think it might be 30 psi
