nothing to terribly difficult . the engine is heavy. I was grateful that I have a overhead lift to manipulate in and out of the frame.
getting the left side of the crankshaft out of the case is difficult , then, putting in back in , you have to draw the shaft through the bearing.
yeah , its a tight fit.
you have a 727 , there is some thing to check . there might be a mark on the piston skirt . its were the counter rotating shaft has hit the piston . when the stroker crank is put in there is a good chance that the piston skirt will strike the counter rotating shaft . its just a mater of grinding a notch out of the piston skirt . there is a pic if you need it .
