Someone told me that a Holley 4-barrel with a custom plenum works great on a 914-4.
I guess if each barrel from the carb goes to a single intake, then they should be balanced.
Should be the same as running dual Webers....(1 barrel per cylinder).

dont let this guy work on your car!!!
trying to run a single port intake off each barrle off a holley will not work.
holley carbs are nothing like any thing thats gets put on these engines.
most holley carbs run a 2 stage throttle, they run on 1 stage called the primary which is only 2 barrles and then through either a vacuum oprerated linkage or a progresive mechanical linkage the other 2 barrles open for what is called the secondarys.
for a holley to work you need and open commom plenum for each primary and secondary set to flow in to.
there are some very large models that run all barrels on a 1-1 opening but those are race only and are not at all suited for street let alone these small displacement engines.
there is much more about holley carbs that has to do with the fuel metering between pimary and secondary for idle and power enrichment that would make that type of configuration not work at all.
running a large plennum like in the picture can work.... i doubt it works very well.
bends in the intake tubes will cause the fuel to drop out of atomization and pool and run through the intake. what will work on dry intake ports does not work on wet intakes.
this above goes for almost all domestic v8 type 4 barrel carbs.
