you will have to change the knock sensor and knock sensor module. the ones for the 305 are too sensitive for the 350 and will set the ses light off. some guys say to change the chip to a 350 chip for the spark curve but i believe they are both the same. i would also change the injectors too. the 305 are barely enough for that motor let alone they have to support a 350. other than that everything else will swap over. hope this helps.
