340 vs 360

Hey guys-------
I know that the 340 is the more sot after engine and is a stronger unit (well back in the day) more expensive, harder to find etc etc
I know the 360 was a dog compared to the 340 back in the day, but one would think with today technology (after market head, intake etc) that you could build it just as strong and quick has a 340.
Or is there some fact that i am missing? Are there any real big disadvantages to going with a 360 over a 340 in todays day and age?
