Putting A '77 Slant In A '64 Valiant?

yeah. I know it is hard to picture when the motor I have is upside down now. But you can get the idea right? I took everything down to the block and the head. I left the oil pan on though to catch some of the crude(if any) that was left in the motor. Once i turned this block over and removed the oil pan, there was a lot of crap in there. Walls look good. pistons look good. Bearing feel good. Just ready for cleanup and paint now.
If you don't feel confident that you have it balanced on the stand, don't attempt to rotate the motor. other wise it may take you with it. I had a neighbor come over and help me. I turned the block while he turned the handle on the stand. Then he put the pin in for me so we could hold it in place. I wouldn't attempt to rotate mine without someone being there.
