Hi, I have a 1940 Ford Holley "91-99" Carburetor that I want to use on a newly rebuilt 1937 Ford V8-60 that is totally stock except for a .030" overbore. My questions are what size fuel metering jets and power valve should I use to get the fuel/air ratio in the ballpark of where it should be? Any help would be greatly appreciated. Thank you.

Is that 91-99 carb a 60HP CARB? you will need to find a 60 hp carb if not, the venturi bore is a lot smaller on the 60 hp verus the 85hp and up carbs, 85-95 carbs will bolt on with no problems , and look correct but way different,will probably run way to rich and just foul out the plugs,if you get it to idle I doubt you can change the jets that small for it to work, but I am sure a EXPERT will weigh in on this, Hope this helps KEEP ON TRUCKIN 37RAGTOPMAN

The correct carb for your 60hp is the 922A. It doesn't interchange with the 59A, which was the "service" replacement carb for all 85-100 hp engines, '32-'48. The main jet size for the 922A are .041 and .043, as compared to the .045-.051 in the other. The 922A has different venturis and nozzle bars, too. To have the engine operate properly, you will have to locate the right carb. There are still some out there, and perhaps someone can help find it.

Post your question over on the Fordbarn: http://www.fordbarn.com/forum/forumdisplay.php?f=4 . 'Kiwi in USA' may respond with an answer as he is into the '60'. Other carb experts there as well.

Most of these carbs will have to located by using Hemmings, etc. You can try Little Dearborn, 888/282-2066. They have been our best source for 60hp parts.
