Jeep 4.0 in 69 Barracuda

To address the carb. & OBD I, carbs are probably more sensitive than any EFI system,and OBD I all had closed loop adaptive learn. GM's Block learn mem.etc.
The GM's & Fords w/mass air systems have a definite advantage over speed den-
sity systems because they read actual airflow in,not calculate it.Also the OBD I's
Open loop idle AND WOT! This takes out adaptability when WE would like most.
The solution for us OBD I speed density users is the adj. fuel press. regulator.
Dial up the press. to compensate for flow improvements etc., and the closed loop
operation will dial back the injector duty per the O2 sensors input at normal drive
conditions, usually within it's parameter's unless you make a drastic change,read
big cubes, super headwork etc. The Grand National guys lived on that method w/
stock system use.You only need a scanner & watch O2 readings at WOT,then adj.
I'm excited to see your progress on this,keep us posted!! :coffee2:

So in this case, I am running all Jeep. Including Fuel injection. Mainly due to how simplified it is. The only challenge was dealing with the O2 sensor. But installing the X pipe solved that as it gave me a single point for a single O2 sensor for the ECU. And I still get my dual exhaust system.

So I took a couple of pictures which will be posted hopefully by the end of the night.
