Recheck your facts.
2006 was the last year the 8.1L was around.
The 6.0L has been around since 2000 or so.
The 8.1L was a powerhouse but was thirsty as crap and sales of trucks with it fell off dramatically as gas prices rose. Meanwhile people were deciding if they needed that much towing or hauling power they'd rather get a diesel and twice the gas mileage.
So yeah, the 8.1L is gone, the 6.0L is the biggest V8 in GM trucks, and the 6.6L diesel is the end all in GM truck power short of the Top Kick trucks and their BEEG diesels.
You couldn't order a big block in a half ton but they would do it the other way around.
