Is it possible to put a fuel injected 4K-E on a 4K block with 3K head and what is it capable of running with the efi on it compared to say a 32/36 weber, i stil want a rumble that a carby can provide, but fuel econ, power, and high rev range is it possible to do and is it worth it? or should i just keep carby on it?? ive got 3K head with street port, 2" exhaust, extractors, whats possible for more power

To make more power you need to either rev it harder, or increase torque. With what you have now, a cam regrind (and dizzy regraph to suit the cam) would be the next logical step. Make sure you have double-row timing chain.
if you have a cash surplus (and a spare motor if this is your daily driver), pull the motor to bits and take it to a machining shop to be cleaned up and overbored. http://www.superjamie.net/ for a good example
