All of these motors are impressive but they all got there ups and down. Its like the old saying goes you have three choices when it comes to a motor: cheap, fast, or reliable, but you can only choose two. You can make a gen one small block (350 or 383) crank out 500hp easily and be just as reliable as that 502 as long as you know what you are doing for less. LS motors are great because they are a very efficient design and don't take much to make good power, but they're going to get more expensive as demand grows for them. You can make an old gen one small block perform just as well as an ls motor in performance and "streetability" for the same amount of money if not substantially less than a brand new ls motor from GM. Same applies for a big block, but big blocks are known for making as much power as you want depending on your wallet thanks to the fact that there is no replacement for displacement (but don't expect them to get the gas mileage of an ls motor, but then again I wouldn't complain ).
