5.9 FI Magnum swap in 73 swinger
Awesome swap, I have a 5.9 in my 73 and it runs great, I'm not using any of the FI or Serpentine because I didn't want to relocate my battery, and I didn't want to mess with FI fuel pressures just yet. Are you putting in the A/C and serp power steering? Did you get the RamVan power steering pump mount or are you using the Dakota/Truck piece? Very curious to see how that fits, lots of Oics please.
DionR/others who want to do a magnum/manual swap -
If y'all wanna use the stock ECM and a manual tranny, why not get one of the 32 tooth crank trigger rings and cut off all but eight of the teeth (pretty sure the gates on the magnum flexplate/flywheel are evenly spaced), then relocate the sensor up to the crank pulley. You'd have to do a very minor bit of wire harness fu to move it to the front but it'd be identical signal, you wouldn't have to do any flywheel fu or bellhousing mangling. The signal that the magnum uses is 8 teeth on the crank, and a two-position cam sensor. All you need is 8 evenly spaced pulses at crank RPM (and probably some predetermined triggering angle for cylinder one). Or, since you would then have a 32 tooth trigger wheel, you could ditch the Mopar ECM And do a Megasquirt/EDIS. More options with less modifications.
