Don't need to swap to get reliable. These trucks are great,first,because of their great reliability. There isn't a part on these trucks that isn't worth rebuilding or replacing with the same part new. I've had my '72 w/350 since '01 and all I do is drive it. I've had to do very few repairs along the way. I swapped the 350 from another '72 I had that I bought in '91 that was sitting waiting for restoration. That motor ran fantastic and was going to waste just sitting,so I swapped it in and put the other on ice. That engine was supposed to be rebuilt when I bought the truck in '91 and it still runs strong. I adjusted the carb (maybe) when I did the swap in '04 but other than that I have never touched it and it still runs great and gives me 12.5 mpg in a 3/4t 4wd automatic.
Check your compression. If it's not so great then you would want to rebuilt it or swap. But,it could just need a major tune-up. You can get a crate 350 from Jegs for about the cost of a rebuild or the sky is the limit
