Pardon my ignorance: why is the 7M-GE so much less efficient?

Alright man. My Bad.

I feel alot better about that now that I know where you are coming from.

Alluminum. That's the biggest visible difference in engines of 07 to even just as late as the 90's. Everything on the new LS2 is alluminum. Everything on the z is the same. Hell the titan and tundra engines are all alluminum based engines.

It's much lighter than the steel that was used from circa 1980.
