83 v8 thunderbird efi swap February 01, 2020, 09:18:30 PM I just bought a 1983 v8 thunderbird to do a 5 speed conversion on. Also I thought it would be some what simple to do the 5.0 foxbody injection conversion on since its already EFI. I did read the sticky conversion.. But it was for 86 and up. Any pointers from anyone that has done this?
