Hey all, thanks for replies.
I am in no way locked into engine choice, I was thinking that way as the engine is very lightweight, I have one, and I have the tuning software for it.
But definatly not locked into that as a choice.
Cost effectivness probably pushes an Italian based engine/drivetrain out the window, not many Italian cars on Australian roads, so second hand cars or parts are very expensive, in comparison to say a Japanese supplied driveline.
The Miura in that article would never be permited to gain registration in Australia, due to the cutting and welding of the floor pan and chassis.
