What fuel injector size do I need? I'm building a new NA LS3 427 and need some help figuring out what size injectors to use. I'm figuring on around 650-700fwhp. I've used the sticky at the top with the injector calculator and I'm coming up with 50-55lbs injectors depending on fuel pressure. Does this seem about right? Also I'll be running one of the new FAST 102 intakes for cathedral heads, what type (LS1, LS2..) injectors will I need?

You need 51lb/hr injectors at 58PSI (stock LSX fuel pressure). The LS9 injectors from GM are 56lb/hr injectors. I think they would be a great fit for your application.
