i'm rebuilding a 350 for a swap soon. i have the tbi 305 now. i've heard people say you need the new computer for the 350. i get why they say that for the injectors because more fuel needs to enter but wouldnt the o2 sensor correct that and add the right amount of fuel?? because thats pretty much what it does if you bore it which i am doing there would be more fuel needed but you dont change the computer the o2 sensor would correct that. anyone have an idea?
