Bottom end

I have herd that some corvette motors have six bolt mains. I know that the new 8.1L have 4bolt mains. So what does the 6.0L,5.3L,and 4.8L have?

The 4.8,5.3 and 6.0 have cross-bolted main bearing. Each main cap has six bolts. Four that go through the bottom of the cap and two that screw through side of the block into the cap.
