Carb is the way to go not doubt, but it sounded like he was dead set on FI ing it so I went that way.
We live in rural shelby county Tn, no emissions here yey anyway, I yanked the tired EFI 5.0 out of the boys stang - went clip, clip to about 300 wires and slapped a carbed 351W in it, pretty easy swap save for the fuel system, had to sump the tank, mount a conventional electric pump, plumb it up the way to the engine bay, dropped the a/c and the smog pump and stuck a C4 where the AOD once lived.
It runs some respectable times for a small camed street motor, 7:50's 1/8 on a good day.
