I have a 500 holley 2 bbl and want to set it up to run decent on my stock 225. Looks similar in design to the holley 350. I took the bowl off of the front today and noticed the jets are way to big for what I want to do with it so I figured Id just swap the car out to a 2bbl instead of swapping junk after junk parts store carbs on there. Those things are a nightmare,DAMHIK....And with the limited suplly of carbs left today we are left with spending big bucks for a new replacement which is really hard to swing the money for. So anyways Im looking for another alternative. A holley I already have here seems like a good idea. The jets are 73's btw. Im just trying to get better mpg and decent power....

Michael,

Sorry to hear about your job, and hope we see you at NW. I will pay for your entry fee for the day if you come and race a Slant car.

IMHO, the Holley 500 2bbl is about the best "bolt on" carb for a performance (but not extreme) 225. You can get great mileage and performance with minimal work. I would start with 68 jets. 73s will actually work pretty well, but 67-70 is best from my experiments.

Best,

Lou
