What size motor does your 1996 Ford F150 XL 4.9 liter have?

The 1996 Ford F-150 XL with the 4.9L engine did *not* have a horsepower rating listed in simple terms like "X horsepower". Instead, Ford published torque and horsepower curves showing output at various RPMs. The peak horsepower was around 150-155 hp, depending on the exact configuration and measuring standards. There's no single "size" motor in terms of horsepower that perfectly captures it.
