Ron, if you want to try an Edelbrock carb they are pretty easy to modify and one off eBay can be had pretty cheaply.
You have to drill and tap the top of the carb to boost reference each float bowl. Also I take the floats and with a soldering iron remove the float mounts. Buy a set of Thermoquad floats cut the float mounts off and solder the Edelbrock mounts on.
As far as jetting goes set the primaries as you would a naturally aspirated motor. For the secondaries, the down and dirty method is to remove the jets. The
