your best bet would have been to get the liquid engine when you first bought it.

I am sorry this makes you upset ,but the reason everyone says that is because it is not cost effective to try and mod the fan 440's ,better to just step up to the lc's. and most do just move up so there are probably not a whole lot of people who can tell you how to get more out of it.

ther are a lot of things you can do  
 advance your timing, make sure your jetting is spot on, do this by checking piston wash. then get yourself a clutch kit from an aftermarket company. this will be your biggest gain in performance period. one good company is ERLADSON PERFORMANCE.  GOOD LUCK.
