How Would You Build This Stroker?

So, just recently I've been reading up on small blocks and how to modify them as I'm trying to expand my knowledge and experience. For Christmas, I got a couple car related books and lately I've been reading up on "How to Rebuild Your Small Block Mopar" and "How to Build Big-Inch Mopar Small Block." Looking at these, a small block stroker engine may not be a bad, future option in my Dart. Going through these books, I'm learning quite a bit. Now I sort of understand why the 340 is more desirable than a 360.

So, here are the requirements. Car is going to see a mix of street, mountains roads (Glendora Mountain Road is about 5 miles away), autocross, and road racing. I'd say most of its time will be on the streets, maybe once or twice a month in the mountains, once or twice a month autocrossing, and once or twice a year road racing. I'm not going to get into anything super competitive, yet. It's not going to be a dedicated race car. It would need to run on California's 91 octane (as other octanes are practically unobtanium or super pricey). Since this is going to be in a handling car, the lighter the better (an aluminum block seems like overkill, no?). And I care about reliability, a lot. I'd like this engine to last for years to come. Let's just say the budget (carb to pan) is $10k (the cheaper the better, but that seems reasonable, right?). How would you build this stroker?

So, I guess here are my questions...

-How much horsepower/torque would you suggest I need? I'd imagine a fairly flat torque curve would be desirable as I will be constantly slowing down then accelerating.

-What block would you use? 360, 340, R3? So, from my understanding, a 340 is essentially a 360 with a 3.310" stroke and a +0.040" overbore.

-What crankshaft and stroke would you use? 3.580", 3.790" (apparently a couple companies offer it), 4.000"?

-Would you bore out the block? If so, how much? What pistons would you run?

-What heads would you run? Is there a benefit to running W2 heads over (lets just say) Edelbrock Aluminum heads?

-What intake and carburetor would you use? Single or dual plane? Aluminum intake preferable?

-Would you use cast or forged internals? Which parts would you choose to be cast or forged?

I'm curious as to what you guys think or what you would build?
