Yes, the Cosworth 3 litre F1 engine wasn't really suited to the sports car scene, and the aero of the F3L was dubious in the extreme. Bruce McLaren commented that the car couldn't work out whether its front end or the rear end wanted to lift the most!
Would make a good aircraft.... Longer wings and all that! 

The later version had a protruding lower lip to the nose intake, which made it look REALLY mean, but didn't do much for the aerodynamics.
I built one as a slot racer way back when, and saw the real thing run in the BOAC 500 at Brands Hatch in 1968.
That made me wonder what it sounded like, so I looked it up on YouTube. Glorious. 
For sure, amongst the 'Big Banger' sports cars at the 500 you could tell when the F3l was coming along, it howled!
But it was 'out-howled' by the Howmet TX turbine car, which suffered a jammed throttle (wide open!

) approaching Druids on only the 10th lap or so and it rammed the bank right below my feet!
