Tearing apart hemi 5.7, machine work worth it?

YouTube just saved me a grip of cash and work.
I love the viper, and want to see it under my hood.
But that exhaust is so god awful.
I want the throaty v8 sound.

I do have a 360 block.
I do have a hemi 5.7 (block now...see pics above)
And I do have a 318(seized but can be torn apart)

Guess I should sit, think, and stick w one of these.
