First of all, you are crazy. According to my handy CRC handbook
of Chemistry and Physics, Aluminum, for example, has a specific heat
of 0.215 cal/g-deg at 25 deg C and atmospheric pressure.
This is .215*4.184*1000= 899.6 J/kg-deg in MKS units, pretty close
to the original poster's #2. Most metals are lower. The closest
thing to #1, according to my table, is Sodium, which at room temp.
is about half of the desired (?) value. 

Now for the point which prompted me to post in the first place -
why the #$%%& did the original poster ask for this info over the
net? Why didn't he look it up in HIS CRC Handbook? It only took
me a second. He has to wait longer than that to get his reply. I think
some people tend to use their computers instead of their brains a
little more than is prudent, sometimes!

...a favorite gripe of mine, sorry.
