original GT 40 intake

Its weight @ 15.8 lbs would suggest its a bit light for alloy as most single 4bbl intakes for FE have shipping weights ~26lb. However most common alloy intakes today tend to be quite thickwall by nature to allow room to port match etc.

This piece looks like it has been cast in factory cast iron type molds, but its missing the exhaust passage by the looks of pics. Does mag have the same shrinkage factors as alloy, eg could it be cast in iron size patterns?

I wonder if they did a lot of grinding on the inside and then welded the bottom in place?
Looks like aluminum but it's light weight.

The extent of my knowledge on magnesium is going to the desert and throwing old VW blocks and parts on the bonfire. It makes for a nice light show. Sort of like looking at someone arc welding!

I heard back in the 60's a small local scrap yard threw a VW block into the aluminum furnace. Good thing the furnace was in one of their out building because it burned to the ground.

It wasn't me!!
I can tell you that when it burns, you can't put it out and the heat is like the sun.
