As for the wear almost every aluminum engine has sometype of steel or =
steel alloy liners in the cylinders for the pistons to move in.  Unless =
you do that you end up with Vega's.  Any one else know of a car with an =
aluminum block without liners?

    Aluminum does have a coefficient of expansion greater than the =
ferrous alloys and cast iron.  That characteristic is accounted for when =
they design for aluminum. Aluminum blocks are becoming more popular for =
one reason; weight.
    (And vehicle weight is the major player in the quest for greater =
mileage)
