    Tell me more about your fuel injection & engine specs.

      used a cam sensor from a jeep 4.0l. cut the base off of an old distributor and bored out the shaft hole to accept the jeep cam sensor. I later learned that the ford 3.0 cam sensor will fit in the Jeep cam sensor body and is more reliable.

      I guessed that this engine combo is about 450 hp max so I used injector calculators online and found the flow to be 35lbs/hr. looked on ebay and found a set flow tested and guaranteed from a 5.0 mustang.

      I was going to use a gm ls 75mm truck TB but I was going to have to drill the intake, so I opted to spend the money on the Holley tapered bore TB and only drill the intake 1 time.
      Using ls1 coil packs, mounted on the swaybar brackets an made wires ran low to conceal them.

      I made the wiring harness, it was intended for the holley TBI but i went sequential EFI so that was most of the time spent. All of the wiring connectors, fuel pump sensors (all are Gm/ls1 except cam sensor) are from pullaparts.
      I had the air cleaner on an elbow from the TB but when the air temps reached 120 ish, is started leaning out and nosing over so I fabbed up the piping to the fender.
      all in all I have about 2800$ in the EFI setup and man it is a lot of fun!
