Yep, the Edelbrock unit is part number 8856 or here is a link from Summit. $221 Yikes.

I guess I'd like to know what that extra $190 buys me. I just bought the one from NAPA and it was $30. No info on the box about where it was made, but it has a cast part number and date stamp on it like I'd expect from a original. It does say it's rebuilt, so maybe they are just putting new bearings in OEM units.
I should know in a couple days or so if it makes a difference on my Catalina wagon. It will be the only change in the system.
