My 79 is a stock 400 motor and awhile back I decided I wanted to upgrade to EFI. It’s my daily driver with lots of daily freeway miles. Also do some light off-roading (forest service roads, beaches, etc.) and some occasional towing (Quads/Snowmobiles/etc.).
After researching options from scavenging junkyard parts to complete install conversions from multiple manufactures, I finally settled on FiTech Go EFI 4-600 HP (30002). It suited my needs feature and price wise.
Originally, I was looking at FiTech’s 400 HP model ($200 less) but I wanted the timing control feature. Also, I don’t really know full future plans for the engine. If someday I start approaching the 400 HP, I didn’t want to that to be the limit. Anyways, for the $200 difference in overall price of the conversion, I felt the 600 HP model was worth the extra cost for myself.
For fuel delivery, I went with FiTech’s Fuel Command Center (40003). They had a cheaper inline fuel pump but after talking to their support people, I decided to go with the Fuel Commander and not have to run return lines. I also like the fuel pressure gauges. I also did consider modifying tank, putting in-tank pump, etc., but I just installed a new tank, sending unit, steel lines to engine, and electric fuel pump near tank. I didn’t wanted to redo it. I will be hooking up the carb inline electric pump to power off the Fuel Commander, which is powered by the throttle body electronics. FiTech said this would be ok and means both pumps are controlled by the throttle body electronics, which includes shutoff if no RPM detected.
To upgrade to EFI, I also have to upgrade my intake to 4 bbl since stock is 2 bbl. I went with an Edelbrock Performer 400 Non-EGR (2171). Based on another FSB thread of mine, I was told that I can put a non-EGR intake on my EGR engine/heads, that it will just plug the EGR ports on the head. Smog stuff has been removed by PO and the EGR plate under the stock carb is the last thing to go. In WA, I have collector plates on the Bronco so I no longer have to pass any kind of emissions.
My plan is to start with just swapping the carb and intake over to the FiTech EFI. This means installing the Fuel Commander, temp sensor, and O2 sensor. Later I will also change out the dizzy, lock it, and let the FiTech unit handle timing. I will also at some point, upgrade to an aluminum radiator with electric fans and have the FiTech unit control the fans.
I will be using this thread to log my progress as I go, post photos, ask questions, etc.
