Will Ford 39# injectors be enough for a 427 stroker motor? I asked this in the fuel section, but received no responses so im trying this here.
Will ford 39# injectors be enough for a stroked 427?
Got a project going on, and i need to get parts together as quicly as possible. The previous owner of the long block had ford racing 39# injectors....should i bump up to something bigger? If so, what kind?
(I also have an upgraded fuel pump that i will be installing, so no worries there)
Ive been doing some reading and it seems that the ford injectors flow at a different (lower) pressure than gm injectors, so the ford injectors can actually flow beter than a higher number gm....is this true? If so, should i just keep these?
I checked out the calculator for injector sizing, but i didnt even know where to start bc im not sure of the pressures and such, so any help would be greatly appreciated.

those are rated at 43.5psi
our fuel pressure is 58psi
most injectors are rated at43.5psi...however some are not, so just check. Those should be fine, but how much power do you plan to make?

Thank you all for the input. I have a friend that is trying to help me out and had some stock LS3 injectors. And it has just come to my attention that people are using adapters to run ls3 injectors.
Here's my question, will I need these for my application?
It's a 24x lq9 with a an ls3 intake, ls3 heads, ls1 coil packs. This setup was running in the previous owners car and I have his wire harness as well.
Also, Is there anything I should be looking for to make sure this has been done correctly? Some threads mention harness adapters while other mention only need injector height adapters....
Here's what I'm currently working with (but have access to the LS3 injectors):
