In my opinion, the four barrel does a much better job of atomizing the fuel, but the NAR-9b flows a lot more air.

As for the 800 build below, you would need to disclose what RPM range before a carb could be chosen.

Good Luck!

Max rpm of 3000, prob 2000-2500 normally. I have a na7 and a na9 to choose from.

My best guess would be a 7. Low rpm. If the carb or manifold frosts over go to the bigger 9.

We have an updraft 4 barrel zenith on our 800ci Moline. We like it very well. We tried a Stromberg 9 and couldnt get it dialed in as well as the zenith. The zenith runs smooth and we turn 4,000 at 18MPH track speed on gas.

I assume it has to be updraft, if it's legal for you an upside down Holley with modified metering block and float bowls will be better than anything else.

The Predators work also.

I'd bet that big Zenith is worth more than the cost of a Holley and the work to make it updraft if you can use it.
