they are 450's. And most people say 300whp, but then theres fuel pressure and whatnot to get more

fueling needs are directly proportional to horsepower. Actually you can calculate pretty accurately how much horsepower you have by looking at how much fuel is being dumped an what AFR you have. Fuel curve matches the HP curve as well as long as the AFR is the same.

SOooooooo, 440cc has nothing to do with PSI. 440cc's are good for around 280-300whp staying at a good duty cycle and safe AFR's so as long as you don't want more then 280whp don't worry about larger injectors.
