Ok I know its been done a bajillion times and I know I could search it so please dont tell me that.

I want to take out my 305 TBI and make it either 350 Carb OR TBI if my manifold on my 305 TBI will fit then Im gonna go with a 350 TBI because I have a 350 Carb but I dont want more work by changing the fuel pump or adding on regulators. And mainly I need to know if all the gauges would still work because there electric and there a most have not for any particular reason though just want it to look original in the interior. I just need someone to let me know what I have to do and if you know where the tutorial is on how to do it 305tbi-350tbi let me know
