42lb injectors ok for 402 NA

Are 42lb injectors big enough for a 402 NA? Any suggestions on other injectors? Also I assume a 225 intank fuel pump is needed also, but are bigger fuel rails necessary?

Bigger rails are not necessary.

For my 402 build up I went with the Aeromotive pump and regulator, 42# injectors, and LS1speed rails. Probably a little overkill.

I have 36# on a 346 and they run at 80% WOT at 6600. Perfect.
You should be good with 42.
