    Default Edelbrock 1409 calibration on 460 Ford

    Does anyone know where the Edelbrock calibration chart is located? I am trying to jet my 460 for Denver (5280 ft); I'm using a 1409 600 CFM. I took the old jets out but can't even read the numbers on them. I had to drill and eazy out one of the secondaries so that one is useless.
    I think the boat is running real rich. Boats following me say it smells like raw fuel coming out of the boat and I can only get about 3500-4000 rpms at the most.
    I bought the boat last year and haven't had time to work on it until now.
    Thanks

    I had the 600 edelbrock on my 460 and jetted it where I thought it was running pretty good. I decided to try a 750 edelbrock and the boat just runs, cold starts, and idles so much better. I think my mild cam just needed more air than the 600 could provide. If your air is thin at your altitude then the 750 might be a better choice than the 600.

    Sounds like something other than the carb is not up to par. I'd check to make sure she's firing on all cylinders, compression, etc before throwing money at the carb. FWIW, a 600cfm carb is going to be way too small for a 460.

    I have a 460 w/ a custom cam- 219/224- .494/.510 lobe sep 113*. I have a Weiand Stealth manifold and a 1410 750 carb. I leaned out the cruise a bit(Can't load the engine over 75 hp @3000 rpm) and slightly enriched it at full throttle- It's been years since I did this so I have to go back and see which jets, etc, I am using. I get really good fuel mileage and pull 400 hp @ 5000 w/Legend impeller.

    I actually want to know what the change would be- It runs good at sea level(Delta) and at 2350'(Trinity lake).....But since the BOR has promised Trinity water to multiple people, the lake will never be viable again, so I want to try Antelope lake which is at 5000'. Anyone with info on adjusting these carbs would be appreciated.

    Edelbrock has a tech line that likely may be able to help you both out.
