Before you think about motors, in teh current climate you need to decide, "do I want full rego, or am I happy on club plates"

Full rego you can still go 427 as long as engineer is happy, and your happy to run on BBQ gas (LPG), I think you will struggle to make a 427 on petrol pass required emissions regs, and this is the ONLY reason most of us have not fitted a 427, I think if a poll was run (just for the Aussies) you will find most do not run a 427, but would love to.

Also nothing wrong with FFR route, as long as your engineer is happy to run it, and you can get your hands on required testing paperwork. There are a few on the go at the moment, I would suggest talking to "fellow" FFR owners and pooling together to have 1 chassis tested and "sharing" the results amongst yourselves, after all when an Aussie supplier supplies relevant test paperwork, it is not your chassis that has been tested, but one of the same ones, that was the "guinea pig" when supplier first started.

Good luck with the hunting and deciding.
