Has anyone performed a EFI to Carb conversion on a 89 to 93 5.0?

u will need to get a fuel pressure regulator with a return to tone down the fuel pressure

also a distributor from a carburator car and an MSD Ignition, or you get an MSD Distributor and hook it up to an MSD box.....

also a different throttle cable since its carburated...

thats pretty much it i think

Thanks Magic. I was woried about getting false engine warning lights etc. But I guess one would just disconnect the computer solving that problem. I haven't decided yet if I am going to do that as my block is in the machine shop and the rotating assembly is being balanced.

Hi all! I am also converting my 91lx to carburation. I am currantly running stock, but fully ported heads, b303 cam, fms 1.6 roller rockers, bbk cold air intake, 70mm mass air meter,70mm bbk throttle body,stock lower intake. I removed the egr valve and spacer and installed a little gadget I bought off ebay to keep the light from comming on. I have changed computers, adjusted everything I can find to adjust, but it still doesnt run right. Runs very rich , but kind of goes threw changes as the engine warms up. any ideas? I bought an Edelbrock Performer RPM Air Gap intake and a Quick fuel 650 carb, but havn't made the change yet! any help would be awsome!

I am converting my '89 to a carbed 347 stroker. Although I am in the build stage right now, all my research has shown me that the computer and all it's associated wiring gets totally removed. There is a web site http://www.jason.fletcher.net/tech/efi-carb/efi-carb.htm that is dedicated to carb conversions. Take a look. I have a friend that undid his 87GT and did as I said above. Go for it and good luck.

Quick fuel owns or vice versa , Proform that makes carb main bodies etc... they make complete carbs and are for sale in summit etc as far as i know they seem like a good piece and i havent been told any probs with them as of yet

 

[grnsking]

summit sells a H E I dist for 5.0. the only drawback is it is taller than stock dist

Or you can use a 85 Mustang GT dura spark and plug your MSD box into it.

I chickened out of installing the carb and went ahead with the fuel injection on my 331 Stroker build for my Coupe. Everything turned out great. My main reason was fuel economy.
