Intakes arent expensive i would purchase 1 and if you need a carb i can ship you a holley 650, needs rebuilt but does work you pay for shipping.  I would use the edelbrock airgap intake or a performer RPM as a second choice.

but to answer your question yes it will work, prolly going see quite a bit of performance drop though.

Why go to a carb?  Is fuel injection not easier and better at producing low end torque?

FI sucks for the most part. Carb setup is cheaper and gets you more horsepower. I would recommend Edelborck RPM air gap, 600-650 Holley carb, 1" spacer, Holley blue pump, MSD distributor, MSD 6AL, shorty or long drop headers, some good exhaust, gears 3.73's(TC auto rear), and maybe a different stall convertor say around 2500-3000 a nice shift kit and there you have it. You would not believe it is the same car, trust me.

If you just want to make some extra HP, the a dual plane intake, Holley 600, some good exhaust and you will be set for now.

So why exactly does fuel injection suck?  Is it a personal preference or a matter of fact?

I don't know why the carb setup would suck, I guess it's a matter of personal opinion, but there's a writeup of how I did my conversion in this post: http://www.foxtbirdcougarforums.com/showthread.php?t=2984

Its a fact a carb system will produce up to 10 Hp more than a FI, and if you use the correct manifold and spacers produce more torque as well,  Down side, constant tuning and gas mileage goes away,  If your new to carbs i would suggest an edelbrock tuing is minute and lots easier than a holley. rulle of thumb street edelbrock, strip Holley.

84 so it has the cfi  a 2brl carb will bolt to the existing intake.

you will need a regulator with a return line  so you can turn down the fuel pressure. 


i would hunt for an aluminum 4 brl intake and grab you a 600 holley VACcumE secondary.

this is a myth  it has been proven time after time both can produce the same power.

there is truth here but with spacers you have to worry with hood clearance

false, a properly installed and adjusted carb will be near trouble free.
and give good milage if adjusted properly

edelbrock is simple to adjust  but a holley will perform better and is easy to adjust also.

This is not a myth a vehicle with a stock carb will produce more that the same vehicle equipped with factory FI, Now with that said yes you can upgrade FI and get it equivilent but the cost vs carb are not compareable.

Yes you have to worry about space. But most vehicle will handle a 1" spacer

Some truth, I personally dont know your experience with Drag racing or carbs, any prof will tell you Holley for strip they are to tempermental for the street, have to tune them every season. where an edelbrock is a much more reliable carb for the street it does not perform as well on the strip
 
In general a carb will consume more gas being they are onlt controled by your throtle instead of a computer.

I can post the adjustment procedures to both i own holleys and edelbrocks, Yes both can be easy, but holley's are far more unstable and will not keep the tuning so to speak.

Numerous articles and books I have read have stated that fuel injection will time and time again produce more low end torque than their carb'ed counterpart.  Why spend the money on converting from fuel injection to carb, when you can put it into heads and exhaust mods?

My mistake, typo.  I mean WHY spend it on that conversion when you can do something with the heads and exhaust?

I knew what you meant, i think the money would be better spent in heads and exhuast.
