305 to 350 tbi information

I swapped my 305 tbi to a 95 Tahoe motor. I used my intake and throttle body tbi if I’m saying it right. I know it’s not time right at the moment. My question is what else do I need to upgrade in order for my motor to run right ?

According to THIS THREAD on ThirdGen.org, you'll need quite a few 350 specific parts; namely the injectors, spark controller, ECU chip, and knock sensor from a 350 equipped TBI vehicle. These things will likely have to come out of a similar year truck as what you are working on.
