Why I thought you'd never ask
I finished up the ls3 stroker cams the other week and the stroker ls3 polluter is just as nasty as this one is. Exact specs may be released later, but the duration is in the high 240's on the intake and mid to high 250's on exhaust and ground on a 111lsa. Lift is in the low .620's on the intake and high .590's for the exhaust.

Nice to see the compression for the big cam. I could see that helping drivability a lot.
Tuned pretty much all the big cams out there.They all love to buck at light throttle in the lower rpm area's,lower gears. For some reason it never bothers people from the south.LOL Northeast people hate it. LOL

David is having fuel delivery issues I believe. Leaning out up top from the amount of fuel this E85 monster is consuming. If we were going solely off IDC% to indicate how much power the car is making, it would be in the neighborhood of 650-675rwhp. Now that said, this car is not making that much power and it's likely that the IDC% is higher than it should be because the fuel pump can't keep up. I'd like to see 600rwhp and 560rwtq out of this thing and anything more than that is just icing on the cake. Some similar set-ups to this have been making 590-625rwhp/540-575rwtq on stock milled heads, E85 and Fast 102 intakes.
I always tell customers to get the compression higher on their builds. I have so many guys that come to me with 10.8:1-11.2:1 pump gas 408-427 cubic inch stroker engines and they always end up leaving the deal with 11.8-12.2:1 compression. They make so much more power with correct compression it's not even funny. Not to mention the drivability the added compression adds. I tell customers that overlap is a great thing when you go WOT as it makes an almost 5th stroke to the 4 stroke engine, but at cruising speeds and light throttle applications, it kills efficiency and makes us hate driving our cars. Adding compression combats the inefficiency it adds and makes driving much more pleasurable.
