Default What HP to replace stock fuel pump?

looking at around 440-480 with the fun button on.

will this pose a problem with the stock fuel pump??

You will need to replace the stocker it is only good to about 400-430rwhp. 42# injectors will suffice.

racetronix is selling a kit, sounds like, that retains the stock function, including direct fit and bowl-filling venturi effect, with a walbro pump. i found another kit from full throttle speed that does the same thing, with the Walbro fuel pump, again, for 100 bucks less......

anybody have any insight into this?? what is the appropriate change? is a kit needed or can the existing hardware be moved over to the new pump, perhaps with a sleeve for the smaller diameter walbro??
