Ford doesn't advertise changes that don't make any difference. HP and torque are the same, rev limit is the same, exhaust and intake are the same, etc. Some of the pieces may have changed, but as far as Ford's concerned it's the same engine.Has ford confirmed the engine changes for the 19-20 gt350? I see it’s published on mustang6G but I haven’t seen ford physically come out and say those changes have been made.
