Default What size injectors will I need?

I'm trying to put a parts list together, and I was wondering what size fuel injectors I'll need. I'll have about 400 hp as an estimated all n/a. Suggestions on a fuel pump would also be helpful. Thanks.

255LPH should work fine. What is the combo?

Yes 255 for the fuel pump but he said injectors

You may be able to get away with 30# but I would get 42's

Well that was a real clear answer guys... lol. I figured 42 would be too large? Soo 36# injectors? Any certain company reccomended by anyone? On fuel pump as well.

What do you have that is going to give you the 400 HP.

If that is true, go with 30 lb injectors.

36 lb injectors are no longer offered by Ford Racing.

if your doing a h/c/i youll have about 300rwhp. so in all honesty 24# would do you, but i personally would go with 30#, thats good up 400-450 hp.

Id go with 42's. With 400hp your gonna have your injectors running close to or exacly at 100%, with 30's, run 42's and than you want have to worry bout it.
