Default Re: Engine swap on 65 GMC 2500 305 V6

Our thought is to also swap intake from 305 to the 351 as long as the port sizes match. and use the 351 carb on that intake minus the governor. The other idea I thought about is if possible, swapping the jets from the 351 carb to the 305 carb if the carbs match in order to get the fuel flow for the larger engine.
