360 build recommendations please...

Ok guys, I've searched and read several different engine build threads and would like to get some of your thoughts on what I'm looking to do. Here's my story:

A couple years ago, I rebuilt a '77 block 360 for my '89 Ramcharger truck and went more of a low-end torque build. Forgive me, but I don't remember EXACTLY every component I used but this was the build:
.30 over, line honed,new bearings all around, don't know the part number or brand pistons but final CR is between 9:1 and 9.5:1 for pump gas (sorry -can't remember). Stock crank, engine balanced, hi-flow oil pump, stock 4bbl iron speadbore intake, MP electronic ignition, CompCam XE262h-10 grind, windage tray, non-smog thermoquad (larger primary bore version) rebuilt by DemonSizzler to the specs of my engine build, J heads w/ 2.02 valves and 3 angle vavle job, stock valve train, performance springs. Hardened seats, new guides, seals, etc. Stock connecting rods.

The engine has less than 10,000 miles on it, and in my 6000lb Ramcharger w/ 33" tires and 3.91 gears, it moved pretty well. Anyway, I'm going to part out the truck and want to keep the engine for my 73 Duster. I have a Performer RPM intake, so I was planning to use that and dump the stock intake. Other than that, I guess I'll be looking for a different cam too. The Duster will be in stock trim with a stock rebuild 904, 8 3/4 rear, 2 1/2 exhaust and headers.

My goal: Nice street car that runs low 12's to high 11's

So, here are my questions:

1.) Is my goal realistic? if not - what should I expect with this build? What do I need to do to get these times?
2.) What cam should I use - all street/no track time
3.) what rear gears - again street only car
4.) I am considering a home port job on the heads - are templates available or is it not necessary?
5.) What torque converter stall?

Sorry for the long post and thanks.
