I have a 1979 Galaxy with a cracked block due to not being winterized it is a mercury/gm 305 serial # 5322779. I would like to purchase a long block either a 305 or 350. But I have a few questions.<br /><br />1) Where to get it? (I am in north GA)<br /><br />2) Is it just a regular automobile engine?<br /><br />3) How much should I pay?<br /><br />4) Can I swap it over from a 305 to a 350?
