| RE: Carb selection for a 390 Mustang |

| Carb selection can be an emotion filled opinion fest for sure. So here's mine with as little emotion as possible. The facts...I've had problems over the years with Holleys indeed. Especially with the GT 600 CFM of '66-'68. Leaking floats, needle/seat probs, throttle shafts, etc. But I've had good ones too. I had an excellent original 735 on a CJ. It worked well always. Oh....yes 600 CFM is plenty on a standard/mild 390GT and I believe vacuum secondaries are best for all around performance. Now as for Edelbrocks...I love 'em! I've run three of them. I wouldn't say they're right-outta-the-box perfect. I did have to read the little booklet that came in the first 750 I bought(for that same 428CJ) and then buy their little tuning kit from Jegs. Called Edelbrock tech line about a bog/stumble I was having off the line. The tech guy was extremely friendly and helpful. He even hinted to me about the up coming FE Performer RPM. Anyway, his recommendations on step up spring and metering rod selection did the trick the first time. Oh, and I do remember reducing primary jet size. All of these changes were made with the carb on the intake with absolutely no gasoline mess flowing all over. My ET/MPH were the same as the 735 Holley. Of course, I had good luck with a jetted up '62 4100 600CFM Autolite too. So what do you like..blonds, red heads or brunettes? You got a try a few before you know right? |
