in need of carb swap info please!
hey all, I have a 1987 Bronco w/ the 351 h.o. 4 bbl carb. I am looking into replacing the holley with an edelbrock 1406. here is the info on the carb:
600 cfm, elec choke, jets primary: .098, secondary: .095, rods .070 x .047, step up sring yellow 4 in high. Has timed and full vacuum ports for ignition advance.
These are the questions I could use some help with:
1. How will this carb effect performance on stock motor? increase, decrease, or about the same?
2. Will I be able to pass emissions with this carb?
3. Will fuel milege stay the same, increase, or decrease?
4. Do I need any adapter plates or other special parts to install other than gasket?
Thanx in advance for the help!

1) it should increase a bit.
2) It should, mine always have.
3) Should increase.
4) NO, You may need an air cleaner spacer to raise it a little bit to clear the fuel line unless you buy a "banjo" fitting.

Why in the world would you want to take off the BEST carb. out there to put on that edlebrock JUNK? I have an Edlebrock on my 78 351M and I can't wait to finish the re-build on my Holley so I can throw this edle-JUNK away!!! The only edlebrock I would consider is the "truck avenger", if you haven't heard of it...go to SUMMITRACING.COM. Only thing with summit is the price is 4 hundred and something and J.C Whitney has it for 3 something!!
Don't do the swap....you'll be sorry!!!!!!

I and several people I know have had nothing but problems with Edlebrock carbs, Never had problems with Holleys.
I fact, I was going to rebuild the motordraft carb off my 83, and rejet it for a 302, but them I found an old 2-barrel holley that I had in storage, So I'm gonna rebuild it and drop it in my 82.
