I am getting ready to paint the block in my 78, and want it to be the correct color. All of the parts stores have both GM Corporate blue and plain GM blue. They are almost identical, but the GM blue is a little darker and the other a little brighter/more turquoise. I think in the Eastwood catalog, they list the corporate blue as what came on 50's and 60's 6 cylinders, but a a few posts in here got me wondering if that was correct??? Help!!!
