The Series III is only the L67. The L36 is still the Series II. The only difference is the L67 has a better blower now. The M90 was redesigned and it is more efficient. So it makes 260hp and 280lb.ft. The L36 still makes its 200hp, and 205 in the Bonneville. It makes more in the Bonneville due to a better exhaust.
The L36'* still have the plastic upper intake like always, because the engine has not changed at all, it is still the Series II. The L67 (Series II & III) don't have a plastic upper intake because of the boost. Nothing is changed here. The only difference in the Series III is the blower.
No plastic upper intake

The only reason H cars had 5 extra horses is they don't have the massive tailpipe kink at the converter.

I read in this months Car and Driver test on the 2004 Grand Prix with the 260 hp Competition Group option that the boost is now 9.5 psi instead of the Series II stock 7 psi. That has got to make the 20 hp difference!
