Can anyone who has a old GM parts book please list the part numbers for the service replacement fitted blocks in terms of the 68 RAII and then the 69 and 70 RA4 , because these 3 fitted blocks should have the TRW forged pistons unlike the 400 motors that what we now call the RAIII motors.

Thanks in advance!
