Here is a bit of interesting info
The new LS2 Mag kits will have an SC inlet to accomodate the LS2 90mm TB.
A simple swap of the inlet and TB resulted in over 20 hp increase (Rumors of maybe 40hp). So it seems as though I am not on the wrong track there.

The Mag does have an exhaust port that runs the length of the rotors (unlike the Fords), so while some cleaning up may help, it won't be as drastic as the Fords. The inlet, bypass and manny could also use some work. Anyone know the bearing sizes on a Mag. I wonder if ceramics would help keep the heat down a little? Nineball...What is the size of your blower pulley? I am listening to everyone, just determined (somewhat) 
LOL 600RWHP Wow if thats real. My 427 made mid 600's to the FLYWHEEL @ 4 to 5lbs. Granted mine was one of the first large cubes to run a 112 and others may have better combos now. My motor made 587 Flywheel HP withOUT the Maggie. But I'd have trouble beliving 600 Wheel HP at that boost level. My SS Silverado was faster than I expected with the Radix. I also had a fair number of issues with it and got rather poor service from Magnason. Mine didn't like being spun at 6500rpm with a 2.8

Could you answer a couple of questions?
1) Is the 427 in your Silverado with the Radiix?
2) What problems did you have with the blower?
3) What is your boost at in the SS? and does in hold or drop at higher R's?
4) Did the rear set of 8 rib pulleys get swapped out?
Thanks
