I think the car Brockbank had in mind with this beauty is Graham Hill/Guy Edwards’ 1974 F1 Lola T370 Ford.
It wasn’t the only car that season to stretch the envelope in terms of airbox design. I’m not so sure about the aero advantages but the size of the mobile billboard is of course considerably advanced, that must have filled Embassy with joy, even if the race results did not.
Lola fetishests will know the F5000 T330/332 donated some of its DNA to its F1 brother while the look of the car is very much like the ‘75 F5000 T400 – with the long-lived T332 the pick of the bunch.

Checkout the details of the car in the Lola Heritage site – worth an extended visit; Lola Heritage These shots are all from that site, what is lacking are captions identifying the circuits…
