ten thousand dollar limit...
If it's a stock block, sell it & get a big bore block. 434" type motor will give the most torque.
With the big bore block you get the best of both worlds. New crank, rods, springs, lifters, cam for sure.
Heads you can get used, if you know where they are coming from. Just my thoughts, good luck.

or get a 350 4 bolt block from a GM company and get a good hydro or solid roller setup with some nice AFR or dart pro 1 heads and have advanced inductions work them as well..... get a victor jr or dart single plane intake along with a 383 stroker forged eagle/JE setup and have it balanced..... get a good engine builder to assemble it and be on your way!
those are 2 good ways to go about getting "pleasing" power from a GM small block NA!

or if you want to put a little more cash at it

If I had 10,000 to spend on an engine alone, I would build a nasty big block on a 300 shot.
The combo would be:
Iron block
Iron heads
Single plane intake
950 carb
Forged internals
2 stage plate kit spraying 150 out of the hole, and another 150 after the 60 ft.
Big solid roller cam and supporting valvetrain.
Just my opinion.

but for a street warrior I most diff would go with a 406ci roughly 525hp and peak torq of 550 at 4500rpm on pump gas
I'm going with these guyz, all forged shortblocks under $4500.00

Plug one in and fly.
Wanna make your ride fly? Just plug in one of World Products' 540 c.i.d., 580 hp Merlin crate engines. These Chevrolet ground-pounders really crank out the torque--625 ft.-lbs. of it, in fact. That's more than enough to make the competition get small in your rearview mirrors. World builds these engines around their 4-bolt-main Merlin III cast-iron block, to which they add a 4130 forged-steel crankshaft (4.250 in. stroke), 9.5:1 forged-aluminum pistons (4.500 in. bore) with 4340 forged-steel I-beam connecting rods. Next up are Merlin rectangular-port cast iron heads with Manley stainless steel valves, plus a Merlin 360 degree, single-plane aluminum intake manifold, and a Hardcore-modified 870 cfm Holley 4-barrel. The valvetrain features a high-performance cam, aluminum roller rockers, hydraulic lifters, 4130 pushrods, and a true roller timing set. Ignition components include an HEI distributor, 8mm plug wires, and Accel spark plugs. All engines are assembled with Clevite bearings and top-quality assembly components from Fel-Pro, ARP, and Manley. They are internally balanced and come with a Hardcore CNC-machined harmonic balancer. Each engine is carefully broken-in, and then run on the dynamometer to certify that performance levels meet or exceed published specifications.
