Re: '70 LT1 Alternator Pulley & Fan Finish
Sam, I am not positive as I've never read where anybody has had original parts analized by a lab.
I think that the 70 LT-1 Deep Groove pulley was Cadmium plated or Clear Zinc, and the fan was clear zinc.
Todays platers used a brightner solution after the zinc plating. I'm not sure that was the case when these parts were new, thus they tarnished much faster.
Just my .02
