It will be hard to ONLY make 1300hp with any of those combos.
I have a 500" -1 motor in my turbo car. And a Procharger on my SRT challenger. Both are diffrent animals.
It's hard to choose what type is better.
If you have the $$ and want it running soon then the Procharger is the way to go. It reuses your headers, and comes as a bolt on kit.
If you want to save a little $$ (not much) and can fab up your hot and cold plumbing, and don't mind all the little do dads that go along with a turbo. Then figure out the learning curve of what changes in the tune (everything) then a turbo is pretty neet.
I think if your going to stay carbarated then I would stick with a Procharger. And if your going to use a good stand alone EFI system like Fast or Holley then turbos start to shine.

As for what combo on the street I would go the 4.15 crank combo. Hooking the 4.5 crank could be difficult.
