Steve,
Not sure what you mean by this ???? They are both the same exact castings. The 305 cranks have more metal machined out of the counterweights but other than that they start out as the same piece.
I tend not to take chances on balance. The first time I would put a 350 crank in a 305, I guarantee you the thing would vibrate ...
Why even take the chance anyway ?? Balance it and be done with it.
There are also too many variations in stock piston weights to take a chance. Some of the late model 350 pistons are really light compared to the early ones. If I don't know where a crank came from, I will recommend balancing it, period.
Just my opinion,
