No GT40 upper, it is butt-ugly at best in the later ones in my opinion. The part I am making is to replace the whole upper plenum with an oval air cleaner shape and weld the TB transition to the passenger side of it. The GT40 lower manifold and the throttle body won't know the difference. I may lose a tiny bit of lower end torque but will pick up some top end where the EFI is a tad weak, both compared to a carbureter.
