First, be sure you can register car without having to meet '94 emissions requirements. Most guys use '68 - '75 blocks to avoid this.

Drive train wise, most typically used is the T-5Z close ratio (2.95:1 1st), or Tremec T-600 close ratio (2.87:1 1st) 5 speed.

Flywheel is the same for all 351W's. 157 tooth, 28 in/oz. Clutch is 10 1/2", and interchanges with late 5.0's, and 351W's.

Bellhousings are not the same. Any bellhousing off a late 5.0, T5 equipped Mustang will work with the T5Z. Tremec's have a different bellhousing, and you usually buy the bellhousing with the trans.

Hope this helps.
