What Engine to go with

So it seems that I should go with either 340, 360, or 408 stroker. I have read alot of good things about the 340, such as it should be the Hemi of the small blocks. I haven't found alot of things on the 360 or 408 stroker(except for dont order a blue print one). Maybe I haven't looked in the right places. The 340 seems to make a pretty decent amount of power more than the 360 in stock form, but would a high comp rating like a 10:1 on the 360 change that?
