Jeff,
I don't think you need a special cam for webers, but rather the webers allow you to run a bigger cam than you usually would without sacrificing tractibility. Case in point is one of my friends in Titusville, FL named Don Parnell who has a Contemporary with a 351C. He's running 12.5:1 compression, webers and a Comp Cams 292H (I think) bumpstick. On pump gas. The engine pulls strong from 3k rpm and he turns it to 7500. Yes it has a wicked sounding lope, as he's running 244 duration at .050". He swapped over to a holley 4V carb setup while rebuilding the webers and as expected the motor just coughed a sputtered with the common plenum and weak booster signals. I would not have believed it if I hadn't ridden in the car and witnessed how tractable the motor was. He hasn't had it on a dyno but he estimates 500 hp. Buy my point is it's the webers which let him run such a large duration cam (it's only got about .550" lift), which allow him to run such high compression on a "street" motor. So cam selection is very important for individual runner induction systems. Of course, as you said, all of the other engine (and vehicle) specs must able be taken into account as well.
Bernie, those are impressive numbers from your 289. Please let us know how it works out when you talk with that company and what kind of cam specs they recommend. Are you planning to keep the compression the same?
