A 292 is a mean engine espeacially for an AD Chevy. I think if it was my project I would go for a Yellow and polished look... yelow block, polished aluminum valve and side covers, chrome alternator, ceramicoated stainless headers, aluminum intake, etc. I would leave the starter and fan black. I don't like those anodized aluminum fittings for the oil, fuel, and pcv, So I would stay away from those. Those are my thoughts... but it may not fit with your theme.
I hope more people chime in to give you more ideas, and or photos!
