PEr conversation with Oracle support couple of years ago, you have two alternatives:
Give the maximum allowable buffersize on the box and import it
OR
Write some program to bring LONG datatype to database.
First option did work for me. That time I was bring 8.0.x database to 8.1.6 Not sure if something changed in between to deal with LONG datatypes.

It depends upon the amount of memory you have on the box.
Use a large BUFFER size. This value also depends on system activity, database size, etc. Several megabytes is usually enough, but if you have the memory some can go higher. Again, check for paging and swapping at the OS level to see if it is too high. This reduces the number of times the import program has to go to the export file for data. Each time it fetches one buffer's worth of data.
