If I get this... 2.3 to SBF Bellhousing Adapter Plate This billet aluminum plate converts any Ford 2.3L OHC engine to the small-block Ford bellhousing bolt pattern. This allows 2.3 owners to run the larger 5.0 Mustang clutch components, T-45, T-56, and other manual transmissions, as well as any of the automatic transmissions available for small block Fords. Adapter use in manual transmission applications will require the use of a zero balance small-block Ford flywheel with a 2.3 crank bolt pattern (also available). Includes all hardware shown, as well as an instruction sheet. Price: $200 Shipped ...does this mean I can use a 5.0 T5? Would a 5.0 T5 be too much for the 2.3? Is there any difference between a 5.0 and 2.3 T5 besides how they attach to the engines, like gearing for instance? I've recently come accrossed money and want to convert my '91 auto to T5 manual.
