440 Headers for 69 Dart/What are these?

Hey guys,

These headers came with my 69 Dart Drag car. The fender wells were already cut, so I went with open fender wall headers on my build.

The guy I bought the car from claims he paid $1,000 for these headers. Either he is full of B.S. or these are a rare bird of some sort.

I'm wanting to sell these, but in the sale forums you need a price. I don't know what I've got here, so I'm hoping someone can help. There are no stamps, brand names or markings of any kind on these headers.

Does anyone else out there have these in a Big Block Dart???

If so, what are they? What do they sell for new? What do you think they are worth used?

Collector pipe is 3 1/2 inches in diameter.

Any help is appreciated.

Thanks.

Will
