Suopposedly the Edelbrocks are a carbon copy, except I believe they had an 850CFM variant as well.
What does the edelbrock kit come with? The generic kits are basically a gasket set, with needle, seat, check valve and piston seal for the accelerator pump, and a few other small pieces I can't think of now. If the generic kits had floats, they'd likely be twice as expensive as they are.
Anyways, I am not aware of any particulars to the differences, if any, of the edelbrock q-jet, worst that can happen is you buy a kit, find out the gaskets don't fit, and sell it to me.
That does bring up a good question though...what style of gaskets did the edelbrocks use? There were a multitude of gaskets used with the q-jet, and while the generic kits come with usually three different gaskets for one position (I think it's the float bowl to throttle body gaskets) the carb to intake and float bowl to air horn gaskets are usually specific to the carb stamped number.
