Need advice: 318 or 340 for a 68 Dart?

if this car was going straight to my daughter I would put a /6 back in.

hmm..

lead foot + 340 = speeding tickets

lead foot + 318 = less speeding tickets

lead foot + 225 = no speeding tickets


My vote is still for 318 though. They're fun engines. I've got a couple of questions about the car though. What parts does it have? Rear end, brakes, etc. And what parts do you have for the 318? Complete running engine or is it just a buildable core?
