Hello All,
My son (my70stang) and I are in the process of a 5.0L/5spd swap into his original 6 banger '70 coupe. We have already converted to an 8" rear end and converted the brakes with a Master Power brake kit.
We located a donor car with a 5 spd (manual) and a 5.0L EFI motor. The milage on the motor is unknown. If need be we will freshen up the block and get the heads done. Someone tried to steal it and messsed up the wiring under the dash/steering column, but the CPU is there, wired in, and appears OK, and the motor and wiring under the hood is all good (no damage). I started stripping the donor car ('89 LX conv. 5.0) today, and even have some good extra parts for the swap meet. I figure I did good to get the car for $400.
My dilemma is whether to try and do the EFI wiring into the '70, or just swap out the EFI unit for a carb setup. There are pros and cons for both directions. I am very comfortable with most jobs on cars and have done just about everything myself at one time or another, but this EFI wiring is looking a little scary to me. I don't want his car to be down for months while I try and figure it out. I have studied multiple websites on the topic and know I have options like the Painless Wiring kit (PRF-60510) for just under $500.
I guess I'm looking for advice from folks that have gone either direction. If I decide to do the EFI, which is the best harness to use? I'm not sure I want to try to use (alter) the stock Mustang harness.
If I decide to go with a carb setup, can I use the distributor/ignition that is from the '89 Mustang donor car? What would the best manifold/carb setup be for a driver (mostly stock) 5.0? Is their a way to keep the serpentine system while eliminating the smog pump? Any other advice? This seems like the most straight forward swap of my 2 options.
Thanks in advance for any help you offer - Tom
