Engine Removal and Aluminator replacement I am upgrading my supercharged '11 Mustang engine with the new Aluminator engine from Ford due to the heavier build of this engine. Currently I have 625 hp, but probably will bump it up to 675 or so, and thus I want a little better built engine. My question is 1) I am thinking about replacing the clutch as well - any comments? 2) also am thinking of changing out the 2-piece driveshaft to a single shaft. I would like to handle any needed modifications when the engine is out, so an comments are appreciated. Thanks!
