360 or 340 ??????

Taking the 318 out of the cuda I have a 340 and a 360 available.
Just wanting to make it a neck breaker...:burnout:

Which would you pick?
. LOL!!!!!!!! This topic again!!!! OK, my 2 cents. Is a 360, since there plenty cheap with a longer stroke which will make more torque which is what breaks necks plus it is a nice 20 larger. Slugs are also cheaper!
