The Ebrock performer 750 is still a piece of junk , doesn't matter what fuel is run thru it .
Statement like that is just making you look bad...
My 'piece of junk' has been on top a' 440 for a coupla' decades...
Good idle quality...
Good transition...
Pulls good...
I can get in there and do dam near anything, without even taking it off the intake...
And still looks like the day I bolted it on...
You ought to just dive in...
If a knuckle-head like me can figure out an AFB, I'll bet you could, too...
