A 1971 454 Corvette was rated at 365hp and the same 454 in 1972 was rated at 270hp. The 270Hp is a more accurate rating in real world performance rather than the 365 hp measured in the lab.
Todays 430Hp C6 would have been a monster in the 60's and could have beaten almost anything in a straight line and on a road course it would have been unbeatable.

That car was completely stock (excepting tires which were modern) and the best time I ever saw was mid 13s @ 104 mph.
My 2008 C6 would totally destroy that hemi Roadrunner and there weren't many cars faster than the hemi in 1968.

I had a new vette in '62 (non fuelie), but mostly stock, and I was proud to run in the 13.10s

Indeed. As I have mentioned before, I used to own a 1968 426 Roadrunner with a 4:10 Dana and a 4 speed.
That car was completely stock (excepting tires which were modern) and the best time I ever saw was mid 13s @ 104 mph.
My 2008 C6 would totally destroy that hemi Roadrunner and there weren't many cars faster than the hemi in 1968.

Which car? Apples to apples, a Corvette weighed ABOUT the same as one does today. Most other cars were also similar weights, but if any thing, they were lighter back then.

4 wheel drum brakes with horrific fade - it actually frightened me a couple of times. And I won't even go into cornering...
Whenever someone tells you about the good old days - they're full of it. As far as cars go, today is the good ole days. In 1968, the C6 would be considered alien technology. It's just that much better.

Since 1972 hp ratings have been rated at "net horsepower" and before that is was "gross horsepower". Seems I've heard that you should deduct roughly 25 percent to arrive at the NET number. Not sure if this is correct though...
