Any issues with this shortblock swap i should be aware of?

Chevy made a 302, it came in the early Z-28's & ran against the Boss 302 Mustangs. Basically, it was a 283 block with a 327 crank ( I think I got that right ). So, you could get the 327 built with a shorter throw crank & really have a 305 in your car..... But you would also have the better bottom end of the 327 block... Just an idea .....
