Last year a buddy and myself converted a Ford FE 390 V8 from carb to megasquirt in 14 hours using a TBI.
We started with a assembled and bench tested Megasquirt, then built everything else including modifying the fuel tank, running the fuel lines, installing a EFI fuel pump, building a harness from a junkyard Chevy G van, getting it running with a decent tune up that was good enough to get him to work the next day.....
So its not that tough, although we had done a MS install before, so even if you double your time it will not be more than that.
