About the Cobra MkII 4.7 V8 271

The 1963 AC Cobra MkII 4.7 V8 271 is a rear-drive naturally aspirated coupe of 916 kg with 267 bhp, which works out at 291 bhp per tonne. Rear drive and 291 bhp per tonne make the launch the hard part of the run: 60 ft takes 2.27 s. Against the 14,946 cars in the set it is the 1,947th quickest to 60 mph, inside the fastest quarter, and the 3rd quickest of the 5 ACs here. Its 109.4 mph trap speed sits about where its 0-60 puts it, so it launches and pulls in roughly equal measure. The simulation is trimmed to 2 of 2 published acceleration figures for this car.

Questions

What is the AC Cobra MkII 4.7 V8 271 0-60 time?
The AC Cobra MkII 4.7 V8 271 reaches 60 mph in 4.79 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. That makes it the 1,947th quickest of the 14,946 cars in the set.
What is the AC Cobra MkII 4.7 V8 271 quarter mile time?
13.09 s at 109.4 mph. It reaches the eighth mile in 8.56 s and clears the first 60 ft in 2.27 s. These are theoretical times from a physics simulation, not measured runs.
How much power does the AC Cobra MkII 4.7 V8 271 have?
267 bhp and 916 kg, which is 291 bhp per tonne. It is rear-drive, naturally aspirated, with 4 gears and a quoted top speed of 227 km/h. These are theoretical times from a physics simulation, not measured runs.
What cars are comparable to the AC Cobra MkII 4.7 V8 271?
Closest here on pace: Ferrari 456 GT (4.87 s), Aston Martin DB7 Zagato 5.9 V12 440 (4.78 s), Bentley Continental GT Mk I (4.76 s). Each one can be raced against the AC Cobra MkII 4.7 V8 271 in the panel at the top of this page. These are theoretical times from a physics simulation, not measured runs.
Are these real measured times?
No. Every figure on this page is produced by a physics simulation, not by a stopwatch at a drag strip. The AC Cobra MkII 4.7 V8 271 is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it reproduces 2 of its 2 published acceleration figures. Conditions are the same for every car in the set: dry asphalt, 20 °C, sea level, 1 ft rollout.
