A-460 Block/Heads

[429mustang]

I'm looking for more info/best pricing on the SVO A460 block and Trick Flows A460 heads, anyone know how the block would be as far as street use (cooling, it's solid between the cylinders) and if everything from a regular block will bolt up (water pump/oil pump, brackets, etc. It sucks because I already have a 1970 429 block w/parts at a machine shop, but I want to put out around 600 hp and I don't want to wory about the blocks strength. If anyone had any ideas about stroker/other engine combos for a big block that'll put out around 600hp, let me know. I'd like to build the whole thing pretty solid, but as cheap as possible.
