There is a V6 engine on ebay right now which seems to be a bargain, even of you fly over to look at it and freight it back (my rebuild cost around $6k)
You have to be carefull as many have been bored to 60 thou which makes the walls too thin and causes over heating so to find the right engine to start rebuilding you need to find one with plenty left in the bores - very rare. The one on ebay says its 40 thou so that would be a great buy.
Dont want to hijack the thread but to answer the question new colour will be dark metallic blue with the black outs and stripes (currently white)
