I just had a 383 rebuilt and needed an intermediate shaft.
I bought what is supposed to be a Melling IS63 intermediate shaft.
Is there some secret to getting the correct shaft?
Are B motors and RB motor pumps different?
I can look at it while the intake is off. Do I need to run a depth gauge down in the hole to see were the bottom of the intermediate shaft would stop in the pump or something?
No B and RB use the same Oil Pump drive. The difference is in the deck height. When you slide the OP drive down in the hole , you may need to rotate the crank to get the hex on the drive to line up with the hex on the oil pump.
