340 vrs 360

i have a 69 340 swinger no motor. i was just wondering what people think of putting a 360 in it. the reason is well bigger and i think that a 360 would be easier to find out of an old truck or bus. and suggestions anyone know where to get eather one of these motors. i saw crate motors but i want to rebuild it my way. i am in sc and if someone close has got a motor let me know thanks
