Yes if you have good flowing exhaust on it although the carb is a little small IMHO. Theoretically a 600 should make 425 hp but...
I respectfully disagree with toolmanmike's statement that the cam isn't big enough to need a high stall converter. That cam has to have a ton of overlap with 308 degrees intake and 318 degrees exhaust duration so it probably won't have a bunch of low end torque and it's gotta be pretty rough idling. A high stall is definitely needed. Not only to improve performance but to allow it to idle in gear at a decent rpm and not tear the u-joints out shifting it into gear. If this were a 416 stroker I'd say you don't need a high stall but it's a 340. A good 2800-3000 stall would not only make it more pleasant to drive but make it come on like a bear.
The Lunati cam I have in my 360 has the same duration at .050 but much less total duration so the overlap is much less and it only pulls 8" of vacuum at 800 rpm in neutral. If I didn't have a loose converter in it I'd have to have the rpm at 900 or higher to keep if from killing the engine when I drop it in gear. And this is in an engine with 20 more cubes than wilnuts.
