What is a cast iron 2bbl intake worth

In about the mid 90s,
I bought the whole dang 77Aspen car with the SSix, A999,diff and a oil-burning core engine, all for $200; AND, drove it home! And it all went into my mint body 1980 Volare that I had just purchased for $100 with a blown engine. Ah those were the days.
Well the engine got built first... and then the auto, and then I found out the diff in my Volare was broke. And then I did the suspension, steering and brakes. And then I gave it a paint-job. And then I had a 15 year old New Car!, that I then drove another 20 years, with nothing but normal maintenance, oh yeah.
I still occasionally drive her around the block.
