Thanks Kelley,
 
I have the 89 rotors but did not clean them up as the one was damaged but the 88 rotor bathtub is definitely cast.  I was going to use the whole rotating assembly including the stationary gears in the 89 block.

Joe,
      As I previously posted the 88 internal parts (rotors & E shaft can be used as long as you use the
88 counterweights (front and rear)........Just make sure your 88 rotors are truly 9.4 to 1 compression
with the "As Cast" combustion dish and not the 88.5 to 91 rotors with 9.7 to 1 compression with the "Machined" combustion dish...............See attached photo to differentiate the two rotors...........
