Fluid dampener pulley alignment question

You have two choices. Three actually. One is pretty cheap, one is a bit more and last (and best option IMO) is the most expensive.

1. Assuming you have the 70 and later water pump and no power steering or AC I can sell you my water pump and crank pulleys (made by CVF), but you will have to make up your on spacers and you’ll definitely need a spacer between the water pump and the water pump pulley.

2. Same assumptions as above, I can give you the part numbers for the CVF pulleys and you can buy new ones from them. And you’ll still have to make up your own spacers and you’ll still need to space the water pump pulley away from the water pump.

3. You can call March Performance and spring for the serpentine kit they have. They have a part number just for the Fluidamper and it actually overdrives the water pump like it should be.

I just thought of a 4th option. If you can send back the FD you now have I believe FD has a part number that has a recess so you can use stock pulleys.

There is a reason any decent damper is thicker. It’s because mass is one of the elements of dissipation of torsional stresses placed on the crank by the firing cycles.

Because there is only so much room to fit a larger diameter damper in there, you get forced to go thicker.

I’ll take the PITA and expense to fit a tuned damper to the engine over a compromise just to get the damper to fit.

I’ll go see if FD has a part number for the recessed face damper for a Chrysler.
