340ci vs 360ci engine

What would I need to bore a 318 over to make it a 340? Im looking into alot of options and this is one im thinking about when I get my mopar. Im still looking at stuff but in the end I think i'll end up with a 318 dodge charger se. Dont get me wrong A bodies a cool BUT im just looking for a Charger for now. Then onto a Duster or Demon cause they also look cool!

As stated here before, you can't bore a 318 to the 340's 4.04 bore size. If you have nothing to start with, (no cores...blocks/heads, etc...) I would build a 360 for the bang for the buck. Cheaper core block, 3.580 crank vs 3.310 crank = more torque down low where you need it. In the end both 340 and 360 with similar builds can make about the same HP, but the 360 will out torque (and therefore outrun) the 340...
