How much horsepower does a 350 5.7 produce?

Answer 1

Talk about a loaded question. There are so many versions of a 350 factory stock. So no real answer.

Going to soup one up?

They can be modified to make huge hp. We guys tend to over build motors to make hp

The important thing is a balance between torque and hp. Torque rules the street. Hp rules the track. Torque can pull highway gears. Moving hp upstairs makes for soggy bottom end and requires low gears to wind up quick. A real Horror show in traffic. I've driven rough cammed supercharged 350's that are the biggest dogs till they get going. Tried and true mild stuff usually works better when building these.
