Someone on the forum said Ford went back to the 2 valve version in Heavy Duty trucks that still use the motor. The 5 speed torque shift transmission would be nice.
The big trucks all have the 3-valve motor still. What they did was revise the power ratings. Torque went up slightly, and is available at a much lower RPM. However, the published HP is down to 320 HP, also a lower RPM. I'm pretty sure they had to re-rate them at a lower RPM to meet the new noise restrictions for MDT trucks. Ford had to do the same thing to the 6.2L in the cab-chassis trucks. Same motor, some output, lower numbers simply because its certified at a lower RPM.
