Drivetrain loss is not a percentage!. All stock cars will have the same percentage though.

It all depends on what GM was actually putting out compared to what they said. There were improvements from 92, yet the rating stayed the same. Also many GM vehicles will dyno some figures at the wheel, not calculated at the crank.

No one has dyno'd an L27 yet on here, so we're curious to see what you got, since we have no clue....

I'd be more interested in HP, as it'* a measure of applied torque
