Where to buy 426 stroker? Recommendations?

I am looking to buy my engine, transmission and associated parts in the USA and import them here to me back in Australia. And while the interwebby thing is a great start to seeing what's out there, I believe personal experience and recommendations provide a more accurate picture. So, where to buy fully dressed 426 crate motor, Tremec Magnum six speed and all the bits in between. I'm also going from auto to manual, so will need clutch pedal. Wiring harness, front accessory drive, air-con kit all needed if not already included. EFI engine, not carburettor. Thanks all!
what engine platform are you looking for?
