If you want to truly be safe, then swap out the MT-82 trans for the much stronger T-56 magnum XL. A complete trans kit will run you about 6K, but you also get the clutch, bellhousing, and new driveshaft. Another 1500 or so will get a set of 800 hp rated half shafts. Unless you plan on pushing the engine output to 1000 hp or more, then the larger injectors that come with the S/C kit will suffice for the fuel system.
