As long as you keep your foot out of the secondaries you'll be fine. When you start opening your secondaries then expect the gas needle to move. GenIII cars were under powered a lot because GM was afraid the car's unibody would flex and bend too much. We've found they can take a lot more than what GM was willing to throw at them. With a carb'd 305 you're not looking at a lot of horsepower...don't think that you're going to be the fastest thing on the road because you'll probably get beat by some rice burners for now. However, it'll be a good first V8 car and give you lots of room to upgrade.

87 Z28 w/ a 305 was rated at 190 hp.

The sport coupe camaro w/ a 305 was rated at 165hp.

This should give you a beginning point.
