Tell me more about your fuel injection & engine specs.
Well I started the project wanting to make a mostly stock cruiser, but things evolved. I started out with a 440 bored .06,9.5 CR,452 ported heads, the comp nostalga cam, performer RPM, long tube headders and a 750 vac carb. Tuned very well and started working on other parts of the car.....then craigslist happened.......complete Holley commander 950 with laptop for $400.

off cam the carb on went the TBI with a noisy fuel pump on the frame. started tuning...starting was great! got idle and off idle pretty good but data logging with that old C950 was messy. I figured out that it was an 8 bit system and I correlated that to a 486. found one at work took it home plugged it in worked great! data logging like a champ for a couple of days, then I left it on the fender and started the car....bam! I thought I'll just get another one.....good luck.

I got some inspiration from this guy:
http://www.dodgecharger.com/forum/index.php/topic,99432.0.html
and made an offer on a Holley terminator TBI unit and got it.
got the fuel pump in the tank, made a return line and supply line(should have ordered)
Made a crank trigger at work and welded it to the crank pulley. Fabbed up the sensor bracket.

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.
1 wire knock sensors from a 454 truck

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!
