I would say it's not out of the question, but not probable. probably 400-420 would be more reasonable

so u think h/c is the better option?

Last week I made a 445rwhp with a p1sc on a car that had previously made 375rwhp with LTs, TDs, and g5x1 cam before the blower. It made 7psi and the AFR was 11.5:1, but it just wouldn't take much timing without wanting to knock... then tuned with the meth kit to 11.2:1 it made much more, 492rwhp at the same 7psi. That's a huge difference.

Why not just start at 9psi with meth and the mods you listed?

I'm probably wrong, but I heard once that 8psi was the most you could run on the stock block. Is that right or wrong?

You can get away with more if you're running meth injection because it cools the intake charge and ups motor octane. If you're running honest pump-gas without meth injection, 8 psi is as high as I would go on stock compression. That's pushing it, IMO.
