Trying to decide on engine paint color.

[rs74]

I am getting ready to put my 355 together and need to decide on a color. Since the truck is going to be indigo blue and a silverish color I don't want to do the traditional orange. I have a pic of a truck painted the same color except it has the LS engine in it. I have been thinking about painting the block to look like it (aluminum) but not sure it would come out right. Then top it off with the black valve covers that have Chevrolet scripted in red. Anyone know of any good engine paint that would be close to the aluminum. I will also have polished ceramic coated headers to go with. Here is a pic of LS engine.
