This is true, you can also get the S475 in a T4 housing as well. I would stick with 360 cubic inches, an T6 S475 (1.32A/R), and have at it. You will make more than enough power to split the block in this combination. Make sure you have 1/2"-5/8" forward fuel line, along with 5/8"-3/4" return. Twin Walbro 255 external fuel pumps or a single A1000 work well. 50MM WG/50MM BOV is all that is necessary. Aeromotive Boost Referenced FPR is a must. Make sure your converter is up to the task, many companies such as hughes, Transmission specialties, etc. offer great turbo converters with anti-ballooning plates.
Blown71duster is correct about the 5" DP issue, you can run a split 4" DP if needed into twin 3" pipes. It is difficult to do front mount on daily driven Mopars due to torsion bar suspension with limited clearance. In a race application, dumping it into/out of the inner fender is all that is necessary.
You are already forced inducted, so I am sure you have a majority of this covered. Just trying to cover all the bases as their is a big leap from an 11 second car running 119MPH to a low 10 second car running 130+MPH.
If you have any questions, just ask, or join 'theturboforums.com' and start a build thread in the Mopar section.
