340 Vs 360 which is better?

Well, lets see, I at the present time have three 340's that I am building, 69-with J-heads, and two 71's with X-heads. But, in the wings I also have an early 360 bored 60 over, 371 I think, that I plan on building later on. When friends drop around they often ask, what are these, I answer 340's, they always say, Oh boy, thats what I would want if I were building a motor!
