"how he do that?"
Looks like a lot of work! Reminds me of a Pantera built in the 80's that used hand formed polished alum panels in the engine bay. Perhaps even more interesting was the engine on that car: a twin-turbo 427 SOHC running through a Hewland gearbox.
Your pic of the turbo "429 Boss" motor (below) is also reminiscent of that same 427 SOHC Pantera.
Always a matter of opinion, but I like seeing some of these ideas coming back around some 30 years later.
