Help choose engine for my 68 Barracuda

Thanks for all the input.
I'm no stranger to big blocks and Hemi's (turbo's too)
The great thing is no matter which of the three small blocks I use it will look stock.
This is important to me because the car is so damn nice!
I have decided to use the 360. I will put the 318 in storage. I will sell the 340.
I will keep you posted.
