Default Injector Question
Will stock LS1 injectors work with my 99' 5.3? If so, will it handle a 225/225 591' 112lsa, headers, exhaust and intake?

btw: they are 28.8lb injectors

No, the LS1 injector connectors are different from truck applications. But you can use 8.1L injectors, which are 30lbs (IIRC).

The 8.1L marine injectors have the Multec plugs just like the truck injectors - they are a direct swap and are 42#/hr.

I have a set of 8.1 32# injectors, direct swap, no modifications.

Just need to tune for the increased flow.
