The track hasn't changed. However sports cars have gotten much bigger, and heavier. It seems to me that the somewhat overweight Jaguar would probably lose to the lightweight Cobra if they were both on the same tires. Sure there are a lot of new modern features on the Jag, but truthfully physics can't easily be denied on a track, and power to weight ratios do have an impact. In other words, I am not really surprised that the Cobra is only 2 and a half seconds slower at Lime Rock.

I can't really believe a 1964 270-hp muscle car is only 2.5 seconds slower than the brand new 380-hp sportcoupe with all the modern equipment and tyres. That's definitely impossible.
Maybe the track layout in 1970 was shorter than it is currently?
