Hopefully someone here can give me some advice been working on an old 54 with a 235 straight six. When I bought the engine someone had already gone through it and so I installed it. The engine has turned freely with no issues. Put oil in and spun oil up to the rocker arms which looked great. Then turning only with starter the engine bound up. Not immediately but after several days of turning slowly turning the engine to adjust all the rockers and I was about to close it up. I did spin the oil to the top consistently over those several days just to make sure there were no oiling issues. The transmission is currently not in so I was able to put a breaker bar on the fly will and it is boundup pretty good. I didn't want to force anything so I thought I would start asking questions. What the oil Pan off I could see that everything looks oiled well and I can't see anything out of the ordinary.. I pulled the rocker assembly and all the lifters and rods move freely. At this point does anyone have any suggestions as to what I could try next to figure out where the problem is.
