Hahaha, hey guys, thanks for the warm welcome. I have seen a bit of content on each of your project cars already and I'm already enjoying each of your contributions.

Yes, this chassis has been configured as a RHD vehicle already. All of the others I've seen are LHD. I haven't quite decided which is better, although I suspect with RHD I can set up a dead pedal effectively (not sure I will need a foot rest in a car with such body-hugging seats though... From a legality perspective, the choice is mine.

I already have a red hot Holden V8 (coincidentally also 383ci, although it's certainly not an SBC) lined up for my Torana, so I will probably stick with the Chev motor in the Manta, and probably the standard transaxle honestly. I realise that the suspension geometry isn't very sophisticated, but I've heard some reports that they work okay. Are LSD's available? Is the Corvair transaxle nice to shift, and strong enough for a reasonable motor?
