350 hp out of a fairly stock 340

I have a 340 and I can say it no way makes 350 horsepower even thought its not stock. I think the 275 factory rating is pretty accurate for a totally stock engine.

I'm not mean enough to hit the red X for this, but I will have to say that you are wrong about the 275HP. It has been discussed here a zillion times. If the 340 really did only make 275HP, why did it beat SOOOOO many muscle cars back in the day on the street and on the strip with much higher HP ratings?
