Misc info: C5 Magnuson supercharger, LS6 heads and cam. If you decide to go with a roots blower, make sure you get a hot rod style as it will make the installation much easier. The Maggies will fit under a L88 hood. Also, highly recommend Speartech for your wiring harness. Asked all the right questions and I ended up with a harness that fit perfectly into the car. Finally, a 700R4 automatic tranny mount will bolt up to a T56.

I've already done the LSX swap, but am now swapping for a 4l60e. What did you all do for the output yoke on the trans? Curious what I need to do for the driveshaft as my TH400 had a much larger yoke.
