So the question is here is what do i have to do to fully convert my tpi for a 305 to be able to run on a 350. is there kits? also if i do this im also switching over from a carb so do i need a new wireing harness?

 

what do you have so far? youll obviously need the mechanicals, a new fuel pump, the harness, the computer, lines, sensors, the works.

as far as switching from a 305 to a 350, to my knowledge, the only difference in the two is the injectors. 305 runs on what i believe is a 19, and the 350 wants a 22... but i wouldnt swear to the numbers. should give you a good idea though
