How much HP can a 12 valve make?
Adding a P7100 to the first generation 12-valve engine effectively takes the truck’s horsepower capability from 350 rwhp to 600 rwhp. For those kinds of gains it’s definitely worth the hassle of hunting down all the conversion parts you need.
What does a 12 valve mean?
The 12-valve Cummins, officially the Cummins 6BT, is the engine at the bottom of the family tree of diesel engines (at least in pickup trucks). Its simple, straightforward design is a symbol of reliability, solid engineering and tractor-style torque.
When did they stop making 12 valve?

What is so great about the 12 valve Cummins?
What made the Cummins so popular was the fact that its peak power and torque was insanely usable—in fact, the redline is only at 3,000 RPM! The 12-valve was able to get respectable fuel economy while producing torque figures never-before seen in an ordinary pickup truck.

How reliable is a 12-valve Cummins?
The Cummins 12v/6BT is widely regarded as the best and most reliable diesel engine ever produced. These engines are extremely simplistic, operating with mostly mechanical components rather than complicated electronic ones. The simplicity allows for massive power potential in conjunction with ultimate reliability.
How many MPG does a 12V Cummins get?
All five trucks we own average 29 MPG highway, and 24 MPG in town. Cummins 5.9L has the fuel economy, speed, and the power to pull.
