340 exhaust manifolds

You should be able to find the 71+lh and 72-73 rh for under 250 if you look hard.

The early ones get stupid money. I sold a set to a member here for around $300 or so because he helped out on some other things. The norm is closer to 450-500 and up range.

Early ones don't work much if any better than the later manifolds.
