Sell the 340 or build it

For some, the 340 carries a certain street cred and they will want to be able to say they have a 340 in their car.
To me, I just want something that performs well. A stroked 318 will wipe the floor with a stock 340 and look the same if dressed with the 340 manifolds.
The money that some will pay for a 340 often buys you a LOT of 360 power too.
