351W HP?
I recently bought a '91 F-250 4x4 with a bad 351W. (blown head gasket) I will be replacing this motor with a rebuilt 351 and just for the sake of curiosity, I am wondering what kind of horsepower I can expect from an EFI 351W?

351W HP?
IT depends...a `91 351w had 200hp and 310ft/lbs. That would be a speed density system. A 94-newer Mass air system had 210hp and 330ft/lbs

A speed density setup has a map sensor above the fan. and a mass air has a sensor on the air hose next to the box.
