Can I and how do you turn a 360 into a 390!!!!!!!
 

I have heard that you can make a 360 into a 390. Is this true and how. I currently have a 75 390 and i beileve that the block is shot. I have not pulled it yet. I think that I threw a rod cap because I have a few dents in the oil pan and oil and water leaking out of it now. I think that the block is cracked. I also have a 76 360 that i was told was a 390 until I pulled it out of the truck and saw the 360 sticker on the valve cover. Is there a way to make a 390 out of the 360 to get more power out of it for pulling a horse trailer. How is a 360? I heard that they are puuches compared to a 390. Or should I just rebuild the 360 and drop it in place of the 390? Any help would be greatly needed.
