Edelbrock Carb Calibration Kits

[72bronco]

<br>I was wondering if anyone had any experience using the calibration kits for the Edelbrock performer carbs. I have a #1406 carb bolted to a performer intake sitting on top of my 302. My engine is basically stock except for a set of headers and a Mallory Unilite ignition. <br><br>Overall she runs very good with plenty of power. I advanced the initial timing to 12 degrees and now it idles better and has better acceleration. However there is a little bit of a stumble if I stomp on the skinny pedal. Plus it still smells like she's running rich even though I've adjusted the mixture screws as lean as practical. <br><br>I'm thinking that a calibration kit might help to tune the carb to my application. I figure somebody around here has used one of these kits before and can tell me the best combination of rods, jets, and springs to use. Otherwise it'll just be a process of trial and error I guess.<br><br>The kit for the 1406 carb contains the following:<br><br>Metering Rods (Pair)<br>.070 x .042 #1450 <br>.073 x .042 #1455<br>.073 x .047 #1456<br><br>Metering Jets (Pair)<br>.095 #1426 <br>.098 #1427 <br>.101 #1429 <br><br>Step-Up Springs (Pair)<br>3-inch Hg Blue<br>4-inch Hg Yellow<br>5-inch Hg Orange<br>7-inch Hg Pink<br>8-inch Hg Silver<br><br>An yes, I know that some of you guys will tell me to convert to fuel injection instead. That's my long-term plan, but until I have the $$ and time this will have to do. Any help would be appreciated.

Someone posted what they used from the kit on here a few months back. I would search for it.<br><br>I have the kit also and never used it, I ended up getting a Q jet.

I have the Carb Kit and it made all the difference in the world with my Edelbrock carb - well worth the investment. Get the off road needle and seat as well

For the amount I paid for my "junkyard" efi (86 mustang with lincoln wiring) I could not have bought an edelbrock carb and a 4 barrel manifold. It runs great. <br><br>Its funny, every time I am on runs almost all the carb guys tell all the fi guys "man...I have got to get FI" I am not bragging I am just very happy with my junkyard FI.<br><br>IMO If you sold your carb, your manifold, and your distributer on Ebay, and you were willing to to deal with Junkyard parts and a MAP system (easily converted to MAF later) you wont be very deep in your project, especially with all the money your about to drop on edelbrock parts. <br><br>I guess I am the guy who said go to FI. Good luck either way.

Back in the old days when I had my Eddybrock , I went through the same thing and ended up using the orange spring , the off road needle and seat and moved the accelorater pump down to the lowest hole . I tried different metering rods as well as jets but ended up putting it back to stock . The important thing is that you don't change too much at once unless you really know what you are doing . This will allow you to see what each individual mod has done . Technically , I have always been told that a stock 302 should run at it's peak with a 500 cfm 4bbl carb . Good luck and don't hesitate to call them boys at Ebrock for help .

As Howie said - calling Edelbrock is a good idea if you need a place to get started.

If you get lost on tuning that E-brock or Carter or whatever , get the Carter book , lotsa info . I got mine at Wal-mart . Like the man said make ONE change at a time !!
