I am running a 3x2 on my 292, as much as I love it, they are painful to get synched if you leave the PV in the secondaries, and as mentioned there is way more power potential and reliability with a modern 4bbl especially with some of the intakes like blue thunder or a mummert.
The 94s like I have are also prone to leakdown etc. that said I love my 3x2 very much and tinkering with it and it's required starting rituals with how much to pump or not is endearing.
The opposite side of the 94s do have some ability to run a kickdown. I am running a TH350 behind mine so don't require one, but a little creativity and some spare bracket kits should get you there.
However, I am always amazed that during shows, folks will walk past 80k show cars and want to talk to me about the y block and 3x2.
Bottom line is that there is nothing about strapping 3 carbs that were basically obsolete 50 years ago on a car, but who said hot rods have to make sense?
