No way would I consider a big block for any application under 650HP. I say 650 Hp because once you cross that HP threshold, you get into aftermarket LS blacks / heads, and at that point things get expensive. Under 650HP, I would do a LS motor but would not mess with the dry sump LS7. For a LOT less money you can do a wet sump LS3 based motor, make the same power and save a ton of plumbing and expense. For just the cost of the LS7 engine you can do a wet sum based 600HP motor including all the goodies needed to install it and make it run.
