1971 340's True HP?

Hi all,
I have a 71 H code Dodge Demon & they reckon it came with 275hp from the factory. I've heard a lot of Chrysler made their muscle cars hp underrated for insurance purposes. If that's true what would be a more accurate hp figure for the 340's.

Cheers,
Glenn.

NHRA rated the 340 for classification purposes at 310-320 hp, and there were some that said production engines of that era varied between 260 - 315 hp. 340 peak torque overall.
