How much h.p. Does a 66 289.ford engine produce2? - 1

Enough to do the job it was intended to do.

Depends on a few factors. The 289 was available with either a two- or four-barrel carburetor. The two-barrel version produced 200 horsepower. With the four-barrel carburetor, the engine produced 225 horsepower. The special version of the 289, called the high-performance model, produced 271 horsepower.

Probally not much if it hasn't been rebuilt
