This is really a loaded question. The 8" converters can be made from very loose to very tight. To say it won't work would be a mistake.
A converter is a torque sensitive device so in your case it may make low stall numbers at low blower overdrive and get higher with more overdrive/ nitrous.

The best bet would be to try it , accumulate data then make changes if necessary. The car is fairly light and I think you should be just fine . After some runs reply to this forum and im sure we can help more.

Hope this helps, Hutch
