ok, my friend has a '72 bronco with a 460, carbed. my other friend might be parting out a '90 F350 with a EFI 460. how hard would it be to put the fuel injection set-up in the 72 bronco? he can get all the wireing and sensors, but will it be more of a PITA than its worth? will the stock EFI work with a slightly warmed over 460? any info is much apreciated.
