i'm kind of in a similar boat. I plan on a a turbo for my 10.5:1 iron head 355, but a bit scared of the compression with 91 octane. I plan to run meth, but it'd be nice to be able to get by with just an IC. Its about 430-440 hp motor, so only planned on about 8psi with a t70.
If you don't mind using meth/water injection, i'm sure you can run atleast 15psi with a good tune. I've got a book by A Grahm Bell (not that one) and i remember reading that with 10:1 and meth/water you could typically go up to 25psi.
