What all would be need or involved to go from a 3.8 V6 to a 5.0 V8?


Asked by Shane Jul 02, 2020 at 02:08 AM about the 1993 Ford Thunderbird LX RWD

Question type: Car Customization

Proud owner of a  '93 Ford Thunderbird with a 3.8 V6.    My question is this,  
how much work would be involved if I were to replace the current engine with
the 5.0 V8? I was told it would be fairly straight forward except I would need to
swap out the motor mounts,  *which I would have anyway regardless.*

If you use an engine from your model year or newer, the only problem would be going from a six to an eight. You'd probably need to replace the computer for that.


I would say engine, trans, mounts, wiring harness, ecm, rear axle, driveshaft, and exhaust. Basically the whole drivetrain.
