Fuel injection questions

TBI fuel pressure is about 12-14psi. If you can, you could run a holley blue/black regulator and dial in 7 psi holley or 5 psi Edelbrock. If you got all the electronics, slough them off to a brave soul on the sale board. I bet more than 1 person would be interested in the entire TBI setup even if it had a hacked harness (like me!) You can megasquirt even a TBI, but the ECU should be more than willing to run a stock 273/318 as it can adjust duty cycle to meet engine demand as long as the O2 sensors are hooked up. Now I dont know what it uses for crank sensor or cam sensor but it shouldnt be too hard to figure out. Even an MS1 can do it (dont know about Mopar idle control on an MS1 though, but you can put an external jeep idle control valve on it and run it like a Ford in PWM mode) and the MS1 are pretty cheap, either to buy or make. The schematic and source codes are out there, about $30 in parts, and itll do ignition too.
