69 340 and 4 speed trans

I am from Sullivan WI and I am looking to sell or trade my 340 and cast iron overdrive A-body trans and bellhousing. The engine is a 69 340, deep oil pan, fluidamper harmonic balancer, adjustable valve train, unknown cam specs, M1 single plane manifold. It is an ex race built but not race used engine and I have never had the engine apart except for the intake, It ran very well. I got a car with the engine and was going to put in my Duster a few years back and went with a mild 360 instead. The crank appears to be a 273 crank with a small pilot. I am looking for best offer on the engine/trans. I am willing to trade for an A-body, Dodge truck or run something past me of equal value.
