What do I need to do to convert to carburation?

MadMustang · 11-06-2001, 10:42 PM

Hi. I sold my blown 94GT a couple months ago and the bug is back in me to start a new project. I have my sights set on a 89LX notchback. This time I was thinking of going carburated but I don't really know what I need to do to acomplish this. Like what parts do I need, etc... Thanks for any ideas

why would you want to convert to carb if you have EFI??? carbs are soon going to be extinct... plus they are less efficient and dont work as good on the street...

I have an 87 coupe, 308, carburated. its a 4 bbl holly carb with wiend aluminum intake and it works just fine for me as a daily driver. I have a comp cam that was not compatible with the e.f.i.

I converted my 88 to a carb, saved a ton of money and went alot faster. I still realize that efi has its benefits but for me it was cost. The cost of converting over to mass air, larger injectors new intake, throttle bodies, pumps, etc,etc all cost money. I spent that cash on a stroker 393.
You will need to find a longer throttle cable, and intake of your choice that suits your application, you also need the small braket that mounts the cable to the intake. These can be found on many cars, Granda, Monarchs, early mustangs and Capris just to name a few.
I used my stock efi pump and bought a mallory fuel regulator, used one side to hook into the fuel return side and the other feeds a constant 8 Psi to my Holley. I bought two brass fittings one was 5/16 and the other was 1/4 for the return line.I also kept my fuel filter at the tank, works great and flows like crazy.
I used a MSD Ignition, but a early stock control unit would be easy to locate and use, along with a Dist.
Hope this helps, I don't think your crazy, just adventurous..

I am carbed, if you clicked on the link in my signature you would see that... it does work just fine on the street, but if i had a car with efi already i think i would stay that way... but i do admire your decision to swap over... it is easier to tune thats for sure and it is cheaper... so good luck and sorry if i sounded negative, its just people are always asking this at the shop and it gets frustrating... sorry
