Quickest way to 600 with a 429?

[429mustang]

I was going to build a similar motor for my 86 GT, I have a 1970 429 in the machine shop, so far it's all apart and I have a victor 4150 intake, aluminum FORD RACING valve covers, timing chain, fuel pump, HV oil pump/swap oil pan. It started as just wanting to build a mild big block, but now I want to build a 514 w/FMS cobrajet or Trick Flow A-460 heads, big solid roller cam, etc. I just don't know if I can/want to spend the money it's gonna take to build it, especially on a stock block. I've thought about an A-460 block from Ford, but they're around $2000, then a stroker kit's around $2000, heads $2000, cam $300-600 if I go with a custom grind (at least w/roller lifters) $200-300 roller rockers, $300 for a bigger pan w/windage tray, then I might as well go with a dry sump while I'm practically building a race motor. It sucks, I just want a fast car I don't have to pay for.
