ARI - You can't mount Holley carbs that have metering blocks in line but you can mount up the ones with metering plates. Here is a pic that I took with a couple of Holley 1850 carbs mounted on to the manifold. You can also turn the carbs sideways and then you could run twin HP style carbs.

It would be a real pain to tune the dual Holley setup like this though since you would have to remove the carbs to take the bowls off. And, you have to change metering plates or drill them since there isn't jets. That would get really old, especially when you're trying to sort out some cross jet issues.


One interesting data point: This combo here with the dual 1850 carbs weighs exactly 30 lbs more than a Indy 440-3 intake with a 1050 Dominator.
