A friend has a Mustang Dyno. We figure about 18%. My 427 usually puts down 440 hp & 430 tq running to 6,700. Good headers and sidepipes and a 14"x3" aircleaner. The last time it was on an engine dyno it was about 530-540 but that was a long time ago and there have been component changes. The atmosphere and other corrections will change things, then SAE or STP output will have significant effects.
As was mentioned in a prior post there are many influences, tune for power & torque and then go out and drive it. Make your last mods, usually carb adjustments for drivability and enjoy it.
