Part 1: I've got an ATI Super Damper for a big block Mopar with a Chevy pulley insert. I believe I got this may years ago because I was going to install a big block in an A-body with either a solid motor plate up front or individual 'bat wings' (I have both). Somewhere along the way I learned (and now forgot) that with either install I needed a Chevy pulley at the crank to line up the belt with the alternator and water pump pulleys. Now for the life of me I can't remember which Chevy pulley was specified. Anyone know which pulley is correct?

Part 2: I am not using the motor plate or the bat wings since the car now has a full QA1 front end and their modular engine mounts allow for a multitude of engine choices. So, I see ATI sells a replacement hub for the Mopar big block damper with the correct bolt pattern for a Mopar pulley. Is it as simple as buying the replacement hub and swapping it with the Chevy hub? The damper is not on site presently or I'd do my own research. Again, any help would be greatly appreciated.

Thank you.
 
I believe the ATI damper hubs are interchangeable within a specific application. You could always give them a call to verify. 65

Sure, but where's the fun in that? I figured there must be somebody here that did/does what I'm describing. Seriously, thanks, I had planned to reach out to ATI on Tuesday.
 

My buddy had a ATI damper on his Small block in his Plymouth Arrow with the Chevy bolt pattern. His engine was mounted with a front plate and mid plate. He used a pulley for the small water pump which is close to the damper and mounted the alternator off the engine plate. Seems like the choices are the small water pump and the large water pump, different space from the damper.

Thanks for the response. Somewhere in the dark recesses of my mind, I remember a discussion about using a big block Chevy crank pulley on a big block Mopar with a front motor plate. The Chevy crank pulley would push the crank pully groove out to keep it inline with the water pump pulley groove that had been bumped out by the front motor plate. The article (?) gives the part number or size of the Chevy Pulley needed. I wanted to find it (article or part number) so when I sell the motor plate and damper, I could include it for the buyer.
 
Spoke with ATI. The inner hub and shell are specific to one another. Oh, and the hub I was considering is actually for a Gen III Hemi - but it wasn't stated anywhere. ATI guy said thanks for the heads-up & they would fix it but I didn't get a free damper (lol).
