Re: 5.0 EFI Good/bad years??
A 5.0 HO is a 5.0 HO is a 5.0 HO, the difference is in the electronics only. The 89 and up use the MAF in-line with the air cleaner and are more easily adapted to work with performance modifications, you can use the 5.0 HO out of a lincoln like H8 did, or use one out of a Taurus station wagon, but make sure you use the electronics from the 89 thru 93 and you shouldn't have any problems. Hope this helps out. Later.
