Complete 6 pack find- not mine

I bought a 72 cuda with a 340 for $1500. It had a complete six pack and its like new. I still have that one. I also picked up a spare original intake when the price started shooting up on these. That cuda also had an original B body dana under it and came with a NOS grill. Sold the rear for what I paid for the whole car then sold the stripped rolling shell for another $500. Wish I could find more deals like that one.
So I wonder if its a licensing issue keeping edelbrock from making the intakes. Sure seems to be plenty of demand for them.
