looking for a built 340 or 360

i just found out that my 70 340 4 speed car has a 72 340, so now i am in the market for a 340 or 360 that is built. i am not looking for 500 hp, but 350-400 would be nice. also, it must be setup to run on a four speed.
as for price, i am flexable, so let me know what you got thanks in advanced

I have a rebuilt very low mile 1971 340 in my 70 duster thats coming out and going up for sale if interested.
it comes with a LD340 intake but no ex manifolds, unless you have more $$$..
then I have 2 pairs.
I'm in socal, let me know.
