I have been toying with the idea of building up an engine to replace the almighty 305. I was curious would this be very hard if i built a 383 stroker. I have read about the different hp ratings people got, andi am kinda in the dark here. Just curious if this would be possible with a 383 stroker

Yes it is possible. Easy even, if you use the right parts combined correctly.
It's all about flow. HP = work per time; work (energy) comes from gasoline molecules; getting the energy out of gasoline requires air molecules; therefore the more air you can move through the engine per unit time, the more gasoline molecules you can release the energy from; and air molecules per unit time can be measured as CFM, cubic feet per minute, which is FLOW, pure and simple.
Every piece of the induction system must be sufficiently non-restrictive to allow the necessary flow; and each component should be chosen to produce that flow at a RPM that is useful in the total car package.
Remember that, about the "total car package". There's more to going fast than just HP. An engine that flows enough to make 500 HP at 8000 RPM will be useless in a car such as a 305 TBI car, with a grocery-cart 2.73 gear and a 1400 RPM torque converter.

Extremely Easy! When building engines its VERY easy to attain at LEAST 1hp/ cubic inch, so without even trying u should nail 383hp, decent heads, decent hyd cam and u can hit 400+, step up to a solid cam, or roller cam, or Solid roller! hehe and u'll make much much more.. My 383 is totally street drivable and i'm expecting around 600hp with a carb and no power adder. Official dyno results will be in a month or so..

my bucket should be putting out somewhere north of 400 horses if I could ever figure out what the problem is. the EFI is acting up because of something mechanical... EFI... love it and hate it
