funny thing is... this is a weekend car and mostly street driven. I do plan on taking it to the track a few times a year but mostly street driven.If it was my build, with 1000hp goal I would do a fabricated housing with a real 9inch, available in any length you want, you could have the center section of your choand change then easily to suit different conditions. My car is a street car no where near that serious so I have an 8.8, 3.73’s and 31’s with a Detroit locker
