418 - 427

What injector size for a 418 and for a 427? Also what other components would vary from the two various sizes. The top end will all be LS1 components ex: FAST intake, AFR heads etc.

42# green tops or delphi's should do the trick. they flow more at our fuel pressure. I think the are both rated at 3 bar

^^^I would agree if this is a NA build. If using any kind of power adder I would go with some 60's.

alright sweet just making sure thanks guys. Well since this is posted in the internal section maybe I should post an internal question...

Is a 418 LS3 more durable then the 427 LS3 I'm sure everyone is going to say they are both plenty strong and I shouldn't worry about it for a NA build but whatever I'm asking it...
