1973 B-body HP 400 & 440 exhaust manifolds 3571068 & 3571071, the heat riser assembly moves freely but the snail spring is broken. Dates codes are early 1973 model year.

What is a fair price to ask with free deliver to Carlisle?

$200-$250 would be fair price.

I got $320 for a mismatched pair ('69 right side and '72 left side) a month ago at the Mopar Alley show. I was asking $350. Also, heat riser flapper was gone. At a big show like Carlisle I'd be asking $450.

It depends on how long you want to drag them around. I had a nice set and it took a while to find the right buyer I think I got 250.00, but that was probably 5 years ago.

I have no intentions of dragging them around, they will only be at the show if a buyer commits first.

I'll list the pair here in the B-body section at $180.00 within a few minutes.....

That would be a good price. I'm going all headers or I would be tempted. Good luck on the sale.

If I still had my P code '73 Charger, I would have bought them from you, but it was sold a few years ago sadly.

in my opinion, a very fair price.
they shouldn't be too hard to sell.

Yes, fair price they should sell pretty easily at that price.
