The 600 Horsepower number will require some serious dollar investment to achieve. The myth of turning any 352 or 390 block into a 428 refuses to die, so I will just say here for the record it's mostly untrue.
Probably the best route for you to take to achieve your goal would be to start with either a 427 or 428 block from a reputable source that will guarantee it to be usable and authentic. Next you need an engine builder who will also stand behind his work and has FE experience. Post where you live and someone on this forum should know of a reputable builder in your area.
You will need a 428 crankshaft, preferably with casting identification IU or IUB. Try to stay clear of the IUB crank as it is a problem to balance in a high horsepower engine. There are rumors of aftermarket FE cranks but so far only custom billet versions are available and they are quite expensive ($2500.00).
I recommend using either Eagle or Crower aftermarket connecting rods. Be sure that even though they are new your builder magnufluxes them and checks straightness and size.
The lightest aftermarket piston you can afford is the next important thing. Your builder won't be able to bore the block until he has pistons. Venolia, Wiseco and Ross are good brands. JE is probably the best but substantially more expensive. Get plasma moly rings.
Camshaft for a 600 horsepower engine needs to be a solid roller type. I would talk to the tech guys at Crane and Comp Cams, see which you like dealing with and get their recommendations for grind. It's going to be in the .600" lift / .260 degree duration at .050" range. You will want serious high quality valve springs, titanium retainers and keepers.
The cylinder heads and intake manifold can be sourced from Edelbrock, the Victor FE will be the intake of choice. Edelbrock's heads are good, buy the bare heads and have them ported along with the intake. You will need serious valves, Milodon and Manley are good brands. You will need the biggest valve that will clear youre bore size. A 427 can use 2.25 / 1.76 valves in the Ed heads. If a 428 block is used then 2.14 / 1.76 is a better choice.
Carburetor needs to be a Holley 800 - 850 double pumper.
That's the basics I would recommend. There are other ways to get the HP you are after but this will be the cheapest I think.
