400's are they any good?

What I was actually contemplating is this; Build a good short block with a high quality crank kit with around a four inch stroke, maybe a little shorter on that. Do some sort of reinforcing of the block, either cross bolted mains or a girdle. Go with either INDY or Edelbrock Victor heads with good parts in them. Keep the compression around 9 to 1, a solid roller cam, and a fairly large Pro Charger centrifical blowing through a carb. No intercooler but use one of the metanol injection kits from Snows or equivelent. I'm figuring a combo like this should be capable of 1000 HP. So what I'm hearing so far is "no", or I'm simply asking too much from this block.
