What is the max horsepower I can get out of a chevy 305?

It is entirely dependent on your funding situation. If you can get sponsorship then 1500 would be within reach. If you only have a few hundred bucks then about 250-300 hp would probably be tops.
 
According to a commercial I just saw about 450-550. They guarantee 411Hp out of a small block. But yeah swapping to a big block can get you much bigger increases after modifications.
 
depends on your budget. If you spend enough money it could get over 1000hp....if they can do it in a honda with 4 cylenders, you can do it with 8.
