Can your swap the mass air system off of a mustang onto a f250 5.0? I'm looking to swap in the 5.0 roller motor anyways and was just wondering what I need to get from the donor mustang for the mass air........ also what year of mustangs do I need to look for! And were the GT's vs the LX ECT. converted to mass air the same time?

Thank you!

1988 Ford F250 4x4, 5.0 liter (soon to be Roller 5.0), AOD tranny, 2.5 Dual exhaust, Headman Shortyheaders, 33" BFG's Mud Terrain

1980 Ford F100, with 1988 5.0L Roller (carburated), T-5 five speed Borg Warner World Class Transmission, 31 spline 9" 3.73 posi , and a bunch more!! 13.78 quarter mile.

 

Can't really answer about the swap a whole lot, but I would watch out for the computer. I'm pretty sure the Mustang has one calibrated for higher revving, and a higher RPM powerband, while the truck one would be calibrated for lower revs, more torque, etc. You might be able to use the MAF sensor, wiring, etc, from the Mustang, but use it with a truck computer.

Good luck with your swap-

yeah that's exactly what I want to know.....

 

I'm open to being corrected if you find me wrong, but..
I don't think you will find a connector for the MAF sensor on the truck wiring. You need to get the computer and wiring harness from the mustang. Also, you will need to do something about the extra O2 sensor which the mustang has.

Problem with using the mustang harness in the truck is that it will be too short to route neatly around the firewall, etc.

I installed a 92 5.0 HO Mustang engine in my 54, and still cannot mount the connectors to the upper intake, like they are on the mustang. There's just too much width between the fenders. However, there's nothing wrong with carefully extending the wires on some of the connectors which won't reach.

both the GT and the LX had MAF systems starting in 1989, hope that helps

 

I was in error on one point. Both the MAP and BP sensors output is a frequency. I had read that the BP sensor was a variable resistor, but found that to be incorrect for Ford.

Both the MAP and BP sensors produce about 160 hz at STP (standard atmospheric pressure and temperature).
The MAP sensor port connects to the intake manifold vacuum port, and the BP sensor port must be left open to the atmosphere.

Sorry for the misinfo.

Remember, the MAP sensor is in the air-density systems and is more critical than the BP sensor in the mass-air systems because the MAP sensor is constantly monitored by the computer whereas the BP sensor is only read at engine startup.
