Exhaust Manifolds

Price any 340 part or car. Last pair of 340 exhaust manifolds I saw for sale were like $400
I swear I bought a pair of repops last year $600 ish? to replace some older ones that I had welded a crack on the lt one and had to remove what ever that stupid back pressure pos that was rattling on the rt. And I’d like to put it out there for all those guys that say you can’t weld cast iron u’d de wrong that’s why they are still in the box. Don’t hold me to the price, I buy a lot parts as god has blessed me with more projects than one guy deserves. The price of anything is subjective based on your discretionary income
