Depends on the year.....early 5.7 coils where coil on plug w/plug wire to opposite bank.....later 5.7 coils are dual coil on plug like the 6.1 coils. I swapped out the early style for the later style on my 2004 5.7. You need 8 later style coils, later style valve covers and later style wiring harness connectors.
