The energy density with the longer chain, higher octane fuel is the same as the shorter chain molecules of the lower octane fuel. Its all about how fast or slow it burns.

The V6 gets away with an 11.3:1 compression ratio with 87 octane because of the control of its direct injected and variable valve timing, etc.. You can read about it here

They say using the same technology on the LS3 engine size scale would come out to 523HP |
Thanks for your technically accurate and understandable explanation. Unfortunately the brain dead will insist they are correct, pay more for octane they don't need and complain there is a "Big Oil" conspiracy about gas prices and go on their merry oblivious way.
