Re: 350tbi on 305

Not really. The injectors in the 350 TBI unit are larger which will cause the 305 to run too rich. However, if you are able to tune the setup then no problem.

Or, use the 305 injectors in the 350 TBI, or swap the 350 TBI fuel pressure regulator onto the 305 TBI unit. Note that you may need a new gasket when swapping the injectors.
