Wait a minute. I know that heat=energy, and that a car runs better at higher
temps (say 200 degrees F), but how does keeping heat in help keep fuel
consumption down. If I had my "ruthers," I would love to have a nice
aluminum engine block and head, and take the 100 pound weight savings.
Also, are the frictional loses from three vs. five bearings a real big deal.

So your car looks better, but I could smoke you any day on the street.

70 MGB with scientifically proven inefficient siamesed exhaust ports inferior
to most engines on the market today
