I don't understand the obsession with the 340. I have both and I am convinced a 360 will out torque and out run the 340 any day. It has more stroke and more torque.
A 340 is a bored out 318 with good heads. Whoopy doo let me go broke buying another one, when I can get a 360 out of the yard and do some work to it and out torque and out run the 340 car.
I had a 74 duster with a 360 and I compared it very closely to my dad's 69 340 cuda. and that's why I believe this.
People are sheep ....if you tell them a 360 is worth serious money then everyone would want one
