He doesn't have oil injectors in his rotor housings. That's an '84+ 13B thing. Stock carbed rotaries have nipples on the carb for the oil lines that feed into the primary barrels.

I only have my personal observations with regard to Holley vs. Edelbrock, no numbers or anything to back them up. Just based on what I've seen, Edelbrock seems to be the better carb, or at least, the easier one to get right. I drove Jeff20B's supercharged FB, for example, which has an unmodified 600 CFM Edelbrock Performer Series, and I was very impressed. The idle, the cruise, the power delivery, were all very smooth and it had good power. Not to say that Holleys couldn't probably be tuned that well, but I do know that Jeff didn't have to do much to that carb to get it to run very nicely. Fact is, though, I'd rather have a Sterling Nikki than either of them.

To the OP: By the way, I forgot to mention OER as another option for blow-through. They're a pretty cool carb based on the Weber DCOE with some nifty improvements and factory boost-prepping. Though after having to remove and install my DCOE a few times with the RB wraparound manifold, I'm not sure I'd buy another sidedraft. The bottom nuts are a pain to get to. :P

I think im gonna give an Edelbrock a shot, I have a friend that messes with nothin but Edelbrock carbs so im pretty sure he'll let me use one for demonstration purposes. I'll update you guys on my results. Is there anything I should look out for after bolting it on, or is it simply just plug and play?
