23 to 18 spline what it takes and how good i'll be!

LOL trust me 23 spline does not hold up to Torque and hp together , heres pics to prove it , this mess happend behind a 528 hemi that dynoed at 696 hp at the wheels with a dana 60 430 gears and Eaton tru trac posi unit , i hit second at 5000 rpm and it detonated complete with with 3 holes in the floor , needless to say it will have a Lakewood bell $ an 18 spline Hemi box when i put it back together .
