You're thinking of Cisco router ACL syntax..  ;)
Your PIX ACL should look like this to block an entire "Class C" IP range:

access-list outbound deny ip any 80.1.1.0 255.255.255.0

Be very careful before applying it to the inside interface - PIX ACLs behave like router ACLs: they have an implied "deny everything" at the end, so unless you have an "allow all" line at the end of your ACL, you'll block everything else outbound.
So your ACL should look something like this:
  access-list outbound deny ip any 80.1.1.0 255.255.255.0
           (...other optional lines if desired)
  access-list outbound permit ip any any   <- last line of your ACL

cheers
