Next stage for my 360 build?

Some of you guys may have seen my posts regarding the 360 buildup for my Duster. The current plan is Magnum heads (still debating buying the tools to do some porting/chamber work), reusing my Lunati Voodoo 256/262 cam (http://www.lunatipower.com/Product.aspx?id=1543&gid=287) with the 1.6:1 Magnum rockers, KB-107s, RPM Air-Gap Magnum intake, Doug's headers, and Carter AFB 625 cfm. First question is, about how much HP and torque should it make AND around what RPM in this form?

Currently my plan is also to rebuild my A-904 with a shift kit and 11" PTC converter and 999 low gear set, with 3.07:1 gears in an 8 1/4" rear. However I REALLY REALLY want a manual transmission and I'm keeping an eye out for the McLeod 5-speed that was supposed to come out six months ago... So with a future swap to an OD manual and subsequent re-gearing (3.73 or 3.91) I'd also like to bump up the 360 into a more serious engine. First thoughts are ported Eddy's and a solid cam, which brings me to my next question, how much HP and RPM can the stock crank and rods handle? And is there a solid cam out there that can still be practical on a 95% street-driven car? I just want to be able to rev this thing out to 7000 because, frankly, nothing on earth (man-made) sounds better than a screaming Mopar V8. I know some of you will say STROKER to get more power but this 1979 block is already 0.060" over and I don't want to risk cylinder wall flexing more than I already am.

And sorry for the huge post, for some reason it's difficult for me to condense my thoughts as well as the rest of you.
