It's 216/224 duration, .551 lift and 115 LSA. I think I'm gonna get it.

You don't want a narrow LSA if you're boosted or you'll leak out your boost pressure. Would make a nasty exhaust note, though!

I was curious how that cam compared to the stock cam and I found these specs from GMPP:

Part #12561721

  • Lift: .467" Int./ .479" Exh.
  • Duration:201° Int / 196° Exh. @ .050'' Lift
  • 116° Lobe Centerline

So, your cam has a little more lift and duration (as expected), but the LSA is stock-like. This will let more boost pressure in but not bleed it out through the exhaust. It should sound meaty and the torque curve should complement that of the supercharger's.

Roger Vinci @ Vinci Performance said it would be perfect for the blower, nasty sounding idle and lots of torque.

I finally got my cold start video this morning. I gotta say I was impressed.
I almost got stopped last night by a local tho. I passed him on a very quiet side street. I made the mistake of stepping on the gas. I saw him turn around and I'm sure he was hitting me with the radar. He followed me into the next town, then turned around. THANK GOD! I def wasn't in the mood last night.
