OA-331 reo Holley 885 ffg vs Zenith #013894 Carburetors

Whats the pros and cons?

Why did the military switch over to Zenith in the mid 1980s?

Is there any power difference?

Better mantinance between the two?

There's not meny topics on the subject. Didn't know they made a Zenith Carburetor till few weeks ago.

I haven't gotten much feedback on other sites.

I'll have to look, I have had a later model replacement in stock for the REO Gasser since the 80's. The Army bought these as replacenent. We had on on a 530A Crash Truck,there was no difference I could notice.
