i dont know what to put the gearbox..
maybe a 4 or 5 speed...
i just need some ides to get the best out of this engine..
i dont care what it is your ideas will be used..
thanks
There are so many possibilities to answer such a question, but if you want more power out of the engine, you won't find it in changing the diff or the gear-box.
Assuming the engine you've got is in good nick and properly tuned, you can't go past a set of extractors and a look at the carby (either something bigger or tuning/jetting the one you've got). Improve the breathing of the thing.
Then there is cam grind, dizzy regraph (and/or electronic ignition), head-shaving to increase compression, blue 12-port head transplant, super-charging, you name it. Spend as much as you want.
All the bits have got to work with each other though; there's no one miracle cure.
I reckon the best place for you to start is Street Machine's Grunt Hunt series (http://www.carpoint.com.au/Tig/Minisite/Minisite.aspx?alias=carpointau&id=7229).
Hope that helps.
