360 block, Indy iron X heads, with some port work, cam was a 500 lift 220 duration, 110 center hydraulic, single plane intake, Ebay stroker kit forged flat top pistons, 9 to 1 compression, MSD distributor, FiTech 600 hp injection system.  6 lbs boost. The procharger I bought used off a big block chevy in a jet boat, made new brackets to fit the Chrysler engine. I don't have the dyno sheets anymore, but it makes around 550HP @ 5,500rpm and if I remember right 500 ft. lbs of torque @ 4,000 rpm.  I was an instructor at a technical college, and we built the engine in class.  When I retired, I lost the dyno sheets.  It runs on 91 pump gas as the FiTech controls the timing.  The timing curve and fuel delivery were modeled using Performance Tends engine software. 
I have different pulleys for the supercharger but I am close to what the unit will handle as far a fuel delivery goes.  I was going to use a blow threw carb but to get it rich enough at wot, it would not idle clean, so I bought the FiTech.
