Anybody know who makes a centering ring to mount an MSD crank trigger wheel on a big block Fluidampr balancer?
One of the rings included from MSD fits the balancer center, but isn't long enough. I read a 4 year old magazine build article online that got one from Fluidampr. I called them and they said it was specially made and they will get back to me. I searched here and saw Mopar65 had one made a few years ago.
This must be a fairly common combination so it should be available, right?

Thanks for any help,

what dimensions do you need. I could whip one up for you

I ran into that exact issue myself years ago, so I designed a spacer which can be used for spacing crank trigger wheels or pulleys. Mancini Racing might have some on the shelf, if not I have some.

I'm running into the same problem. I have the Fluidamper on my B-Block and I want to mount the 36-1 trigger wheel I got from AndyF. But I need a spacer since the pulley mounting area on the Fluidamper is recessed (actually, the damper ring is thicker). I haven't measured how thick of a spacer I need yet but I see the spacer that Mancini sells (http://www.manciniracing.com/bicrpusp.html) is 0.375" (3/8") thick for $47. And Mancini has another spacer (http://www.manciniracing.com/prprpusp.html) that's 0.512" thick and costs $23. The Doty spacer (https://www.dotymi.com/motor-sports/21-mopar-crankshaft-pulley-spacer-.html) is 0.625" thick and costs $41.30.

My plan is to measure how much I need to space out to get a little proud of the Fluidamper ring since I want a clean signal from the trigger wheel. Then I'll buy whichever spacer fits the best. I'll have to check to see if the Fluidamper ring is steel or aluminum. The Doty spacer is the nicest and the thickest. If that was too thick, I could cut it down on my trusty SB Lathe. I see that Jerry mentioned that he could CNC one up for you. I wouldn't hesitate to get a price from him and go that route to get exactly what I needed. I suppose that you might have to fiddle with the pulley mounting bolt holes depending on if you have that one offset bolt hole or not. But I think that the Fluidamper has all the holes evenly spaced.

Of course, once I do all that, I'll have to see where I'm at for the crank pulley alignment with all the other pulleys. At a min, I'll need a shorter crank pulley since I don't want to space all the rest of the pulleys out by whatever I'm adding here. Doty sells v-belt and serpentine pulleys and all the rest of my pulleys are from March so I'll have to do some more pulley alignment engineering.

Hi. Yes I had a friend at work machine one for me. He said it was pretty easy. All I did was take him the balancer and the msd wheel. But I still see MSD doesn't put a note stating you might have to do this.

DMI. Great stuff!

Thanks for all the responses and help. It looks like a spacer that moves everything out 0.9" and a DMI 0.7" pulley would work perfect. The pickup would require minimal spacers and the belt would still line up.
I don't see one that size listed anywhere. Can they be stacked or do I need a custom made item?
