What colour combo in the engine bay?

If you have a lot of chrome or polished goodies or even an aluminium manifold I would stay away from silver on the block. Contrast is the thing whether you go black and orange or orange and silver or whatever. Personally I think the orange block would really pop against that green, then use ceramic coated headers to add a third color. Here is what i did with mine.

I guess it always pays to look at how old the thread is before posting in it... (facepalm)
