aluminum 5.3 vs iron block help decide guys

Ok guys I have a dilema here. Don't know what to buy. I can buy either a 5.3 from a 05 truck with 35k miles on it for 600 bux complete swap less tranny or I can buy a regular 5.3 or even a 6.0 swap complete for about the same. I just don't know if the aluminum swap is good for my 81 short wheel base 2 wd stepper. Any pros and cons on the aluminum block vs iron block besides the weight wich I am not that worried about. Thanks in advance.
