Will a 4.6L V8 torque converter fit on a 5.4L V8?

This guy sold me a different engine they are so identical! The only difference is the exhaust and torque converter. Would you happen to know if the 4.6L V8 torque converter will fit on a 5.4L V8 flex plate?

the 4.6 is a 2005 ford e250 and the 5.4 is from a 2006 ford e250

also what will happen if i use the converter? I have heard some people have done it

Yes, they the 5.4 is just a slightly larger version of the 4.6. Torque converter should swap between the two.

I'm ar 208k miles this car is a 9.5/10 body wise and engine wise so i don't know if i should get the tranny rebuilt too or should the tranny be good if its already made it very close to 209k miles?
  • On a 2000 ford ranger, will driving it without a catalytic converter cause valve issues? My ford ranger has had the cat removed (not by me!) and it is causing an O2 sensor code, of course, and an overly rich exhaust and poor fuel milage. Now, I know it needs fixed and I will when I get the time to get it to a muffler shop, but my question is, will driving it for a little while right now cause any valve trouble or any damage elsewhere?
  • Do I need a catalytic converter? I have a 2000 Mustang Ford V6 3.8L I looked under the car and I did not see 1 catalytic converter, I saw some pictures supposedly I has 4? But mine just has 2 long pipes that just go from the engine to the mufflers and then exhaust pipe. It smells like gasoline when I start up the car. Will this damage anything?
  • How can I remove the 4 bolts on the drive plate attaching the torque converter? Ford Laser 2001 automatic 1.6L There's no window to access the bolts which are attaching the drive plate with torque converter like in camry. Thanks for your answer. My next problem is locking the flex plate. Can I use a flat screw driver to lock the drive plate?
