Re: 3.9l head on 4.0
Infact I'd be sus if the head is r/s...He may have had it there and wants to get rid of it ??? Too high a comp doesn't work on efi engines unless spark advance can be changed..It will ping ...Or run like sh!t...
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
