i think they are good for about 320 whp or so on 41psi static fuel pressure

so does that mean rc 440s are about the same? 300ish?

yup shure does

if I raise the fuel pressure will 450cc support more??

yes. but be careful how much u raise the pressure. More pressure means more strain on the fuel system (pump, injectors, seals etc). A small increase of about 5 PSI is relatively safe, but the more u push it the more u chance failed injectors, leaks, and other things. Much better to do it right and buy new injectors with the correct flow rate.
