    Good morning all

    Is anyone running an Edelbrock 650 on their 390 ?
    I am still having issues. I have the Edelbrock (Carter 625)
    Still having issues. Sick of it.
    Just looking for options.
    If someone gave me a Holley (just to try on there)
    I'd do it. Just to see. Then buy the stupid thing if it worked

    I recommend the Edelbrock 1406 (600 cfm). You don't want too high a cfm. 650 is overkill in my opinion and can cause driveability issues.

      Mr. Byers sorry to hear of your issues and hope you and your family are safe and well. I agree with John, as I ran the Edelbrock 1406 for many years with no issues

        Hello, I always had good luck with Holley 650 on stock Fords, GM"s. Good luck.

          I'd try one.
          The Edelbrocks were the hot ticket back in the day
          I had one of the Chinese Holley's on my Dodge Charger
          That was a POS. But I hear they've gone back to their
          old quality.
          I ran a 780 on my 383 for 10 yrs. Exc for a pwr valve or . . .
          It worked perfect. I cracked an ear on it putting it on the
          440, so I bought a new one.

          But. I discovered last weekend. I have WAY bigger fish
          to fry.

            If you're having issues with your Edelbrock (Carter) check fuel pressure if you haven't already . They never get dialed in with pressure that's too high .
