I remember someone on the list saying something about the tr-7's engines. The
effect
of the statement was the different heating and cooling properties caused the
aluminum
head to "weld" itself to the iron block...
My family got a great deal on an early 90's Sunbird because of a the properties
of an
aluminum head and block...The DPO drove the car in second gear at about 65 mph
down
the highway. The heat, compression, high rpms caused a spark plug to explode
out of
the head. It only needed some shimming and a new head gasket to make a total
recovery.
