Yes. Could use a 4.0. Could use a 5speed but would have shifter in dash of the Mustang. Unsure if t-5
trans is available in it. If using after around 1999 would have to deal with anti-theft in the computer. That can be delete out by sending computer out for changine. Could use a 3.8 out of the later Mustang. Say around 2000 model same deal on computer but bellhousing same pattern as 5.0 way I understand. Have a buddy using a c-4 behind a turbo 2001 model. Could do like me 3.2 SHO in a Mustang but I don't recommend. A nightmare but doable. Just everything else around house broke, Jeep, 89 Mustang, MG, washingmachine, and trying to build workshop. Good luck Maurice
