The 305 and 350 standard crankshafts have 2.450 main journals and 2.100 rod journals. The 305 stroke is 3.48, exactly the same as a 350. The material however is different as the 305 in a cast crank and most good ( trucks and Corvette) 350's are forged steel.
You can verify this from multiple net sources.
You should have checked all clearances as you may have a crank that's been ground undersize in a block with standard main and rod bearings. Make sure you have 5.7 rods with correct piston pin locations.

The stroke is the same with a 350 sb and a 305 sb ( 3.48 in.) the bore is the diferrence( 350= 4.00 in. bore.... 305 =3.736 in.) http://en.wikipedia.org/wiki/Chevrolet_Small-Block_engine#305
Something else is your problem.

that all depende on the stroke of the engine you took the crank shaft from vs the engine you are putting it in. If they are the same then it will run fine as long as you do the rest of the assembly right.
