What spark advance curve for MSD and Carb? I just got a '06 LS2 engine from a Corvette that I am going to put in my track car. I plan on running a 750HP carburator on a Victor Jr manifold. This means I will need one of MSD'd programable timing modules. What timing curve should I program in the box. I'm told the LS engines don,t want more than 28 degrees total advance. Any advice from you guys?

If you look in the "conversion & hybrids" section you will find several posts that have proven a carb'd LSx motor can run much more timing...34-ish degrees. The fuel injection seems to be the limiting factor for timing.
