Apparently ATI Super Dapners are a bit thicker than the generic SFI balancer I ran on my wedge.

From the ATI website; I appear to have 917122E which uses OE style timing cover, steel case, and "Not an OEM replacement for stock pulley location." I can't seem to find pulley recommendations on their site. Has anyone run into this before?

Doty makes shorter pulleys. That is what I recommend for my race alternator kits: http://arengineering.com/products/motorplate-kit-powermaster/

How thick is that motor plate?

I have had the ATI hubs shortened on the crankshaft side in the past to align the pulleys work scope
How about using a 426 street hemi crank pulley also first? scope

If using a stock style water pump make sure that
lines up first.. then you can add spacers/washers
to line up the alt.. no reason to make this difficult

So in that case you just need to add a spacer
or a few washers to get the alt lined up.. very
simple.. you dont even need to spend the big
bucks for a trick pulley

I’m concerned about space if the crank pulley is spaced that far out. Just curious what pulley others are using with this balancer. I’m going with Andyf’s suggestion.

I prefer things “tighter” to the engine so I can understand where you’re coming from... the Doty mount on my RB, and small 1 wire alt, I ran his flat pulley on my dampner.

Do you own the crank pulley you show on the
engine now.. is so all you would do is move the
alt out about 3/16".. I build my own pulleys
so it easy for me.. but if you run just the
crank and alt you might be able to cut the
outer pulley off(but maybe not)

Maybe cut down the pulley you have on the engine now? If it is solid you can put it in a lathe and just shave 1/2 inch or whatever you need off the base.

The current pulley is hollow. It's a March 33% under driven with dual grooves. My DMI bracket has all of the supplied spacers plus a few washers to get the alternator where it is. I no longer need the second groove of this pulley (ditched the P-Steering) and someone (or me) will probably need this for another project. I'm not going to attempt to modify the pulley nor further space out the alternator. I don't mind buying a new pulley. Just wanted to know what others are using with this balancer. Doty pulley ordered yesterday. Thanks!

Glad you got it sorted out.

For info purposes I've been using an obscure Moroso pulley on mine. They don't make it anymore so it's better to find something more readily available.

I've been using the Moroso cast pulleys, myself. You can still find them for sale. They have a solid base, and had mine cut down for proper alignment. Just get shorter Allen bolts.

Yeah good point, they do still sell the cast ones. The reference I made was towards the anodized billet one on the left..They still sell that style for brand x but discontinued them for the Mopar applications. I really like that they're solid and can be machined.
