I used a 3310-2 in the 780 cfm version first on an old Ford F250 with a 460 then on an F350/460. It got rebuilt and used on a well warmed 351W in a T-bucket. I finally pulled it when the shafts wore out to the point it was unrepairable without spending lots of dollars. Until that time, it was a totally fantastic carb.
Just make sure when you buy one (or any other used carb) that everything is in good rebuildable shape and all there.
Though I know little (or nothing) about Predators, why would you want to change it out? They supposedly work just fine though don't have the support of millions of Holley users.
