LS3 injectors on my 408?

Will LS3 injectors work on ny 408? Shooting for 500-550whp. Just wondering if they are big enough for my application

LS3 injectors are right around 42lb in size so if you can make them work with your harness and fuel rail I think they would get the job done.

Ls3 injectors dont have the same plug in for the wiring harness as an LS1 injector does. You just need to buy 8 of the plug ins to convert it.
