That is weird. I think it maybe 9.6:1 it would make more sense so it would run om 87 gas easier. I don't know guess as they get more of them resleased and more info someone will know.

Maybe the L76 comes in two versions like the LQ4 and LQ9 and depends on the application.

No the Lq4 replacement in the HD is the LY6 which is rated at 353HP as to the specs of the difference like compression ratio of the two I don't know and would like to know.

I thought the L76 GM had released was off the aussie holden car with the L76 motor. Not the new VortecMax L76 one?
