Default Ls3 Injectors in an lt1?

So after we put a turbo in my cousins 2010 camaro he gave me his old 42 lb injectors. Will they fit with modifications? They seem way to short.

If they seem short they probably won't fit.

Not to mention putting larger injectors in would do far more harm than good, assuming you aren't heavily modded, without programming.

These are facts...I'm doing a H/C and a complete overhaul as we speak. Sending my PCM to PCMforless as soon as I have exact numbers on my install...Im wondering if there is an adapter or any modifications I can do to my rails to make em fit properly. I'm starting to think I'll just let the stockers ride.

Just about any high impedence injector should work.
You might need to get adaptor connectors.

Ls3 injectors are much shorter than stock style LtX injectors you would need to lower toe fuel Rail about 1/2" then change the pigtails aswell.

On a 43.5 psi system they wouldn't flow 42#. LS3 42# injectors are rated on a 58 psi system.
