The Mako Shark was a gorgeous car, I was irritated that Chevy mellowed those looks so much when producing the next generation Stingray.
As for engines, this points out a major difference in design philosophy between European cars and American cars - when European designers want more power they design a higher tech engine, American designers want more power just throw in a larger engine. The Lamborghini engine went from 3.5L (about 210ci), 270hp, to 5.2L (about 315ci), 440hp, in about ten years; American engines went from around 320ci, 330hp, to 450+ci, 450hp in the same period. This is not a judgement call on either, though I can't help but wonder what the US manufacturers could have given us had they followed the high tech approach - a Ford 351 with DOHC and four twin Webers, especially if dropped into a Mustang with fully independent suspension. (I recall the first time I saw a Lamborghini engine, a 4L V12 from a 400GT, sitting on a workbench; accustomed to the 429CJ in my Torino Cobra, about 430hp, I was astonished by this tiny aluminum wonder that looked like I could tuck it under my arm and walk away, and it was 400hp!) But there is a major difference in driving these cars; Euro cars develop their hp in a narrow band at the top of the rpm range, they need those 5 or 6 speed gearboxes and lots of shifting (you won't squall the tires in a Ferrari unless you nearly redline the engine and drop the clutch); big American V8s have a broad power band, that 429 would smoke the tires and fishtail sideways at 3000rpm. Which is better? Personal preference. Ferrari's V12 and Ford's 427FE have both won LeMans.
Then came the late seventies with fuel consumption requirements and emissions controls and suddenly a Corvette 350 was only 250hp while Ferraris and Lamborghinis and Porsches were offering 350hp from 300ci or less ...that met US emissions standards. Throw in turbocharging, which in the US was only for Indycars and aircraft, and the discrepancy was even worse; my '78 Porsche Turbo was around 270hp from a 3.3L six (200ci).
