Well I was talking about the steel crank/iron cam gear combo here http://www.summitracing.com/parts/clo-8-1018/overview/model/chevy-ii
vs
the steel crank/alum cam gear combo here http://www.summitracing.com/parts/clo-8-1016
But I'll go with the alum anyway.

I didn't really consider this in my fall break plans but I guess I have to have the new timing set's crank gear pressed on before I can put in the rotating assembly... duh... So I might not be putting it together until thanksgiving or winter break :-(

Great news on the head Tom! Thanks for the update.
