The other difference is that Honda and Toyota both use a private patented micro-polishing process on liners, pistons, wrist pins, and cams and crank bearings, which GM does not use. I believe they have another process altogether.

Depends on the block, chevies are just all aluminum for the ls1, typically over 800hp they switch to an iron block
Hondas are sleeved blocks but I can't recall sleeve materials as I believe it was done primarily for cooling and not for strength so I'm guessing aluminum sleeves
0w8 would be too thin in the heat here.
