Bolt Pattern on Damper/Crank Pulley
Yes but depending on the year there would be one bolt that doesn't line up. The depth would be the same as a cast iron pump small block. But the 70 and newer aluminum pump pulley is deeper and bigger in diameter. The belt groove is deeper on the Hemi crank pulley
Here is the difference in the pulleys . The one on the left is a 70 and newer pulley on a standard damper. The old trick when running a Fluidamper is install a 69 and earlier small block or big block pulley to correct the alignment as seen on the right. This also made it under drive the accessories. due to the smaller dia. Same bolt pattern depending on the year. 72 and newer are equal pattern.
