I was planning on replacing a 305 from and 86 with a 350. I have a 78 350 in the garage. Will that work or will i need a 350 from a newer year. What else will have to be replaced. I assume that the alternator, steering and water pumps should be fine. The headers too i think. will I need a new carb? anything else. any input would be very helpful. will i need a bigger radiator? thanks for the help.
