You had 2 engine choices. The standard engine was a 4.6L Triton 2-valve V8 that makes 248 horsepower and 295 pound feet of torque. The biggest and most powerful engine was the 5.4L Triton 3-valve V8 that makes 300 horsepower and 365 pound feet of torque.
No Cummins INC company makes the Cummins engine.
Possibly suzuki? Idk if it is the biggest, but their Hayabusa engine is pretty insane.
Ford Motor Company
No , the biggest engine is the 4.0 L V6
Okay- I own a Ford Escort LX, 1994 4-dr, and for all my problems, and help I use this forum site called feoa.net (ford escort owners association), look under "engine swap" and either look for the biggest engine, or post your own topic. It's an amazing site,
