They would never be able to sell it as it wouldn't meet safety legislation, I'm sure.

Personally, I would prefer them to make something new that has the impact of the Countach rather than rehash old ideas no matter how great they were when new.

Don't forget a very potent engine package came from Lamborghini back in the late 80's. It was a factory installed twin turbo 5.2 liter qv rated at 745 hp! 2 Countach's left the factory this way. I think heat may have been a problem but it was making the numbers.
