Today, dollar for dollar, is the 318 faster than the 340 ???

P.S. - CURRENTLY - I have 3 mopars with 360's, and a 4th that is going to get a 360 (yes, I'm pulling the 318 for a 360 :D ). I have 3 with 318's, though as stated, one is getting pulled for a 360. One mopar with a 383. I currently have no 340's, though I wish I did.
