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.

  The upfitter kit is quite a kit! However, GM doesn't want to install it so they give you the parts and show you the door. You get 5 buttons and a separate fuse block as well as some large fuses that got in the battery covers. There were already installed on mine truck but nothing behind them (see the picture). I think the button install would be fun cutting into the plastic but overall, I really like the kit. These are great and can be set to on all the time or switched by the key. On the fuse block you get fuses and relays which makes it easy to connect lights or other high draw devices or gauges. What gauges are you getting? If Banks, they have an OBD connector which makes connecting them easy, speaking from experience. Some other gauge pods will do the same. So far I have Diode Dynamics fog lights and my dash cam connected. Working on more items to connect.
