Carb help * the famous debate and 2x different cars
Well, back to the OP's question. Both of the cars are primarily street driven, correct? If I were you I'd stick the 750 Eddie on the crate 360 and drive it for a while, see what it does for the type of driving that you do - you already have it, you might be surprised. Don't screw around with it. Take it out of the box and put it on the car, do the minor adjustments like idle mixture and idle speeds, get the kick down right and drive it. The back barrels on this AFB style carb operate at engine demand kind of like vacuum secondaries. It's possible that the mechanical secondaries on you Holley weren't doing you a favor except at WOT, and you will find the AFB a snappier carb driving around and at part throttle. If it doesn't work out, stick it on the barge and see how it does there.
I've heard to whining about Edelbrock AFBs , but just in my own experience, I have a 600 on my warmed over 318, and 2 500s on the crossram on my 340 and they have been trouble free over many years (15-20) and many, many miles. They required very little out of the box if you're not into extensive carb tuning (except for balancing the dual quads) :lol:
