4.6 To 5.4 Swap Flywheel

[330McRee]

This is my first time posting so forgive me if I don't really do this correctly. I have a 1998 mustang that's been 5.4L 4v v8 swapped with an 8 bolt flywheel and I was wondering what flywheel would bolt up to it? It also has a T45 transmission if that helps.

Any 8 bolt modular motor flywheel will bolt. 96-04 cobras had them stock and iirx 99-00 gt cars did too.

Easy to source from late model or American muscle.

The only issue you might run into is the difference in clutch diameters. I have a 10 1/2" on my 2v 5.4 but on my 4v 5.4 I went with the 11". just be aware of this when sourcing a new wheel.

Just finished my build.......yes you will need an 11" clutch. Stock gt starter works without issue.
You'll need 4v cobra exhaust manifolds as well.

2001 Cobra flywheel is what I used.
