How much horsepower does a stock 1994 351 Windsor have?

Answer 1

It depends on the type of car it was originaly instaled into and parts like the type of carb. But most likely about 200 horsepower.

Here's a more universal answer to your question and those searching because that above is literally waaaaay wrong...

I have a 94 351w that came out of a bronco and stock all and makes 240hp/330ft lb torque. Keep in mind with this motor, you have so much more room to breath and the least of upgrades like a set of good headers yields around 240-245hp.

Trickflow Heads and good stage 2 cam yields a mere 350hp. heads alone 300hp+.

Looking to at least feel the power, throw some 4.10's in the rear or be ballzy like me a throw 4.56's behind that 5 speed and you'll be making everything piss pants.
