Default 99-04 4.6 Engine Swap

I have a 2000 Mustang Gt and spun a rod.

Need to replace the motor.

Was wondering if any of the 99-04 4.6 GT engines would fit into my car.

I was told i can only swap between the 99 and 00.

Please help ASAP as I found a 03 engine with 38k miles going for 1000 and I really need to get back on the road.

Thanks In Advance!!!!!!

6 and 8 bolt shouldn't make a difference as long as you make sure to use a clutch for a T-45.

ok hold on here... let me think.... you are going to have to buy a flywheel if the engine doesn't come with one. Because your flywheel is an 8bolt and your new one will be a 6 bolt.

The flywheel for the 96-98 (stock comes as 10.5"),which use the T-45 trans, is the same as the flywheel for the mid 01-04 (stock comes with 11"), which use the 3650 trans.

That means the clutch for the T-45 and the clutch for the 3650 would have the same bolt pattern to the fly wheel. The 03, if it comes with a flywheel should be an 11", 6 bolt flywheel and your 11", 8 bolt clutch should bolt to it.

I'm sorry if this doesn't make any sense... I confused myself half way through this and I think I fixed it but not sure.
