Hey G.
I missed your number 1 requirement which was the aluminum block so please notes that the engines listed were regular block. I think you can can meet your budget with the aluminum block. It may be a little tricky if you start getting into maximum bore size pistons since I would assume those have to be custom made.
Here is a site that carries a lot of the ford aluminum blocks
Right off the bat you are starting at $3300, so it will be close. You could go with M-6010-Z351 which has a 9.5" deck height and then you could technically build all the way out to a 454. I would try to find combos that use stadard crankshaft lengths so you can then get a forged crank which can be appropriate for this style of performance engine.
Here is a nice little java calculator to find the bore and stroke combo you are seeking

Let's say you wanted the maximum bore size at 4.155. With 2.75" main journals, you can find 3.5, 3.75 and 4.0 forged cranks readily available. These combos would make
3.50" - 379.66ci
3.75" - 406.77ci
4.00" - 433.89ci
I tend to think that if you go down the non-standard bore and non-standard piston size road, you are probably going to end up in the $15k+ range. I think if you stick to the 030 040 060 stroker kits available, you will have a lot easier time sticking with the $10k cap on the budget. With the aluminum block, 060 pistons are not a worry.
Here are some additional examples to think about. Here is a speedomotive 408. the basic price is $1400.

I would upgrade the pistons to forged for $345. Notice they offer up to 060 with this kit. I would also upgrade to forged crank and my guess is that is $300-$500 more. These combos at 4.06 would produce
3.50" - 362.49ci
3.75" - 388.39ci
4.00" - 414.28ci
probe industry aka Coast High Performance carries several forged cranks and forged pistons for the 351. scat also carries several.

I think most of the components on a Winston cup engine are high quality and so they add up fast. Like the aluminum block above..add that to a set of yates heads you are you over $6000 and you only have 2 of the parts necessary to finish the engine. Add a forged crank and we are now close to $7000. Add a Race Demon Carb and its $8000 and there is still no rotating assembly
You might consider a regular block to stay under $10k. I think it is a good idea to go with the forged pistons, rods and crank if you want an engine that revs 7k+. I personally think the two most important parts of an engine are cam and heads. The AFR 205s are excellent heads...be aware that the exhaust ports are raised .125" higher than stock.

Here are my favorite 10.5:1 cam grinds. Cams preferences are somewhat subjective. I like higher HP cams over low rev TQ cams. Many cobra owners prefer the opposite. It depends what your goals are and where you plan on driving the most.
