I have confirmed a bit of things for my build. I am going with an LQ4(6.0L) I found one local for a good price at a yard. The engine will get new head gaskets, oil pump, cam, lifters, springs, valve seals, etc....
The block and valve covers will be painted Pontiac/Oldsmobile blue. The main reason is that my wife picked the color. The design on the other page had nothing to do with that. The truck will eventually be painted 2 tone, Light Quasar Blue Met (WA9790) with a Dark Gray Met (WA8798), and a Red pinstripe separating the colors.
