Need advice: 318 or 340 for a 68 Dart?

Agree with both of these! My question is, Do you have a 318 and a 340 at your disposal? If not, consider a 360. My pick is a 340, but you may not have access to one, and a 360 would be second best. You want a daily driver, but id hate to see you get your *** handed to you at a stoplight when you have that throaty growl and want to have some fun.
