Anyone Swapped an 1987 5.0 into a bird/cougar originally with a 3.8l? November 02, 2010, 12:15:23 AM As the title states I'm looking for anyone who has an 1988 Thunderbird or Cougar and who swapped in a 1987 Thunderbird or Cougar 5.0. Hopefully there is someone on here. I have a code 67 and I'm wondering if someone else did the same swap and got the same issue. I don't know if it was there before the swap.It's a shot in the dark, but I thought I would try. Quote Selected
