Holley 81 v8 60 carbs
I put a new motor in my model a, and somehow ended up with a pair of holley model 92 carbs, which are the holley version of the famous stromberg 81 carbs. I can't find any information on them, especially regarding stock power valves or jet sizes. I plan on running them on a gear drive intake on a pretty hopped up banger.
Anyone have any information regarding these oddball carbs? They are ford script, manufactured by Holly. Model number is 92 (cast into the side), and have an 81 cast into the rear of the carb. |

Re: Holley 81 v8 60 carbs
The Holley 92 Venturi size is 0.875 and it flows 142 CFM. The stock jets are .043. For power valves I've heard 7.5 as stock, but also folks have mentioned using 6.5, 5.5, and 4.5. This is all secondhand info from the internet but that's what I got.
