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)

Speaking of engine metal, why are most engines aluminum now? Doesn't =
