Holley 94s in particular.

Zinc die cast is my guess but want to find out for sure.

unobtainium?

 

I am quite sure that you are right.

 

I thought that they were pot metal, never thought enough to find out.

 

Money.

 

Zinc/aluminum alloy.

 

Duste01 got it. They're made out of an alloy commonly called "pot metal" which is mostly zinc and aluminum. The different qualities in the metals allow the carb to hold up to the vibrations it will be undergoing on top of a running motor.

 

Reason why zinc is used: holds fine casting details better than aluminum.

 

Zinc (main ingredient of pot metal) or aluminum.

Zinc is a lot heavier with a density of 7.13. The density of aluminum is 2.7. So zinc weighs about 2-1/2 times as much as aluminum. So that might help you guess what metal it is. Pot metal is zinc with some other junk mixed in, but still heavier than aluminum. The melting point of zinc or potmetal is pretty low compared to aluminum, so that's another way to tell what it's made of. They call it potmetal I think because you can put it in a pot and melt it on a kitchen stove.

 

With the price them lately I tghought they where made of gold GREGG
