Must be a emissions thing as well as the ford v10 kinda sucks imo
From Chevy website:
Thundering 345 horsepower @ 5200 rpm
HEMI-beating 380 lb.-ft. of torque @ 4000 rpm(1)
10,000 lbs. of towing capacity(1) — the most towing capacity of any half-ton pickup on the road(1)
Vortec Max V8 Engine Features:
More horsepower than Ford, Toyota, and Nissan half-ton pickups(2)
More torque and trailering capacity than a Dodge HEMI(2)
Vortec Max Performance Pack(3) includes Ride Control Suspension, a 9.5-inch axle, automatic locking rear differential, and a Heavy-Duty Trailering Package.
Deep inside the combustion chamber of Vortec engines, a ferocious vortex is created to generate a better fuel-to-air mixture.
A high-capacity cast-iron crankshaft with undercut and rolled fillets. And to help reduce stress, the crankshaft is internally balanced.
High-flow cast-aluminum cylinder heads that feature a low-friction roller-rocker valvetrain
Electronic Throttle Control to help achieve optimum vehicle performance and efficiency
A Powertrain Control Module that continuously measures input to achieve optimized engine performance and smooth transmission shifts
Coil-near-plug ignition system for a precise delivery of high-energy spark
When included in the Vortec Max Performance Pack.
Based on 2005 competitive information.
Available on select Half-Ton LT models.

These look like the specs of the 6.0 liter. I have heard nothing about them dropping the 8.1. Still way too much demand.

They have dropped the manual transmission option for the 8.1 and dmax, but you can still get the 8.1. Those were just the number for half ton trucks with the optional 6.0
