Hey there! I am new to the forum. I just became an owner of a '74 (I think) sleekcraft 18' with a olds 455, for $300 bucks none the less. With a little love it fired right up but it sounds like it has a spun rod. I added some pics. The first is how I found it. The second at home cleaned up a bit. The third is the head. I wanted to know if the oil return is ported out. I hear the stock is the size of a pencil. This looks like I can stick my pinky into it.
