The short answer is "yes" and in the same fashion as the sbc 350, by changing the crank for a 400 version. The 305 requires some additional clearancing by a machine shop.
The gains in horsepower and torque are not as significant with the 305 as with the 350, due simply to the differences in displacement, but the costs are about the same. This means you will get less "bang for the buck".
The bolt holes are in the same place, but the larger combustion chambers and big valves would probably make the 305 run like crap.
That would be a destroked motor, and would result in a 285.

Roughly 6.2 you just never really hear a 383 by its litters as the 305 is a 5.0 and 350 is an 5.7
If you wanted to put a 3.75" stroker crankshaft with a with a 0.05" offset grind into a Ford engine with a 4" bore (such as a Windsor 351) you could make a 383ci Ford stroker. But as for making the traditional Chevy stroker engine, you can't turn a Ford engine into a Chevy engine.
