Re: Over heating? Black finish vs. Standard Finish
Look at the engines in race cars, especially NASCAR cars. The engine blocks will be painted black for the reason Venice gave. Chrome, or polished will hold in heat. Black will allow the heat to escape the casting better. Just don't sit and idle for long periods. These are air cooled engines and rely on air passing over the cooling fins on the head and cylinder to dissipate engine heat.
