That motor is setup for low end torque, better heads but not better motor.

That motor is just a cam change away from being a great all round motor, the only limiting factor with the explorer motor are the hyperpathetic pistons. But as long as you don't go crazy with the power adder of choice you'll be fine.

The 1999 Explorer engine has 9.05:1 compression, 215 hp and 288 ft lbs of torque. It's not that spectacular of an engine.
