Re: injector upgrade
Even if they're the 17lb from the 3.4, they're too big. Your ECM would need to be adjusted to handle them. You'd just be spewing more gas.

Re: injector upgrade
The biggest that you should run are the 3.1 injectors. I am running them and car runs good, slightly rich though.

Re: injector upgrade
They aren't much of an upgrade. I only have those cause I needed some new injectors ASAP and the JY only had 3.1 Fbodies. Look into the Ford F1ZE injectors.
