Agree with scooberblue, although it doesn't always work like that as some 740cc are grey as they are remanafactured 380's i.e different nozzle holes sizes, same body/internals.
Yellow 440's will get you upto around 340-350 with a pump and reg. Cheap to get 2nd hand but you will need rail adaptors which are £35

you can always get the 440's re-sized and cleaned at a later date of you want more power :
