Can you use 305 tbi carb and manifold on a 350?
hello everybody I'm new here and just just got my 3rd gen for about a week now and boy I love this car more then anything! I know theres a lot of questions and answers here but I couldn't find what I was looking for....I want to swap my tbi 305 for a 350 (which is really common I know ahha) and I'm wondering can I take the manifold and tbi carb thingy from the 305 and bolt it on the 350 no problem? also I know I have to change the exhaust and tune the computer but is that all to it? Thanks guys.

AFAIK there is no difference between a STOCK 305 TBI manifold and a STOCK 350 one.
Which is not to say that you "should" use it; only, that it will work about as well as a STOCK 350 TBI, once the other things, that regulate fuel and timing curves and such, are changed to the ones appropriate to the bigger motor.
Best plan long-run is probably to get a good 4-bbl intake such as a Performer RPM and a TBI adapter. But not "required" to get it working.
