Having some issues with a stock crank shaft pulley lining up with the water pump and alt pulley
The Crank shaft pulley is sitting too far "forward" compared to the water pump and alt pulley
I suspect it's due to ATI dampner being a bit wider compared to stock ?,,,therefore making the pulley sit too far out.....
Any thoughts ?? Is there a different pulley I could use ? I know companies like March, etc sell aftermarket stuff,,,but didn't know if something more "stock" was available ?? Thx, Doug

I found that out too. I used a March dual groove pulley set that they list for the fluid damper (10170 kit) but it was too shallow by about 3/8", so Andy sells a 3/8" spacer (AR140?) that worked, but I had to use longer pulley bolts (ARP 612-1500 1.5" long). The result was close, I think the crank pulley aligned with the power steering pulley, but the water pump pulley needed a thin shim to get everything aligned correctly. On the plus side, I have never thrown a belt yet even when hitting 7,200 RPM.

The pulley from Doty Machine fits with the ATI damper. Stock diameter?

Thanks everyone!! Appreciate all the info and pics Andy,,,,I found the pulley on their website. I don't have the sprocket like setup you have,,,, just the ATI dampener. Think it will still fit ?? Will need to do some measurements on the Doty pulley from their website. Thx.

Difference looks to be about 5/16" to get all the pulleys to line up. This is how much the stock pulley is off from the water pump and alt pulleys Stock pulley is about 2 - 5/16 tall I need something around 2" tall. Hoping the Doty will work. Website doesn't give that particular measurement but sounds like Andy has had luck with it. Just wondering if the sprocket apparatus he pictures affects anything ?? Thx guys !!

The problem with the Doty pulley is, it's a smaller diameter than the stock pulley. Turns the water pump slower. I think it's the cause of my low speed issue of running hot.

I am using the 6 bolt mopar dampener. The effective belt diameter on the stock pulley is 5-3/8,,,, the Doty is 5",,,so 3/8 differential Hopefully this won't be a issue for me. Running a high vol pump,,, big radiator,,, and big electric fan.
