I Engine power was killed by all the regulations starting in the mid-70's. It wasn't until a few years ago that some cars have had comparable power outputs. Auto companies have had to fund massive amounts of research for 30+ years just to get engines back to the power levels they once had.
Engine power was killed because - until regualtion - the approach was ham-fisted -- bigger bore, larger cam, bigger rear diff. pulling the insulation and carpeting, etc.- It was going nowhere fast.
On the other hand, forcing engineers to think -- and in a different way -- and to actually innovate rather than merely iterate is why we have the high output and performace we have now. If left to the unregulated past, the performance gains would be hardly more than that attained in the laste 60s.
Smokey Yunick - a genius with his hands - was able to squeeze lots out of an engine, but there was little inthe way of innovation and technological forward-thinking. The only glimmer of innovation was fuel injection, but even that was ham-fisted. Did you every try driving one of these beasts in traffic -- I dio it on occasion with my Boss and it's a blast for a little while, but.....
Even my Boss 429 cannot do that without open headers and slicks. My 1967 427/435 Vette couldn't do what the S55 does in terms of 1/4 mile (elapsed time and trap speed), 0-60, top end, handling, fuel economy.
