just out of curiosity I dont know a whole lot about engines, but i wondered something. if you took a stock LS1, and put a set of non-ported 6.0 L truck heads on it (lowering the compression to 9:1)..... then you took it and put a blower (8 lb maybe) on it with a 150 shot nitrous kit, what would this yield? a monster? or a slow POS?

I'm speaking from experience. I've worked on somewhere around 30-40 supercharged LS1/LS6 engines. 8psi is right at the limit of the stock components. Sure, you can go higher than that but it won't last long.

8 PSI doesn't mean anything. PSI is a measure of restriction, not power or airflow.
8 PSI on 6.0 heads isn't 8 PSI on LS1 heads.
If your tuning was right on, you'd have a great setup. But it probably wouldn't last.
Check Rob Raymer's forumla out, he was putting 700+ to the ground with a stock motor. Not something I'd try, but he's doing exactly what you're talking about.
My advice: if you're going to all the trouble of FI + nitrous, spend the $2800 at a sponsor and get a small cube forged short block. Well worth the money.
