Well first thing is first, NO you do not need to do a stroker to get that kind of power. It could help achieve that kind of HP later in the RPM band though.

Looking at crate engines, your options are slim to make that kind of power while keeping it everyday-driver capable.

The top Edelbrock package utilizing a GM Goodwrench 350 as the starting point, makes 363HP and 405ft-lbs of torque, and comes in at $6195.00 base price. That engine utilizes a roller cam, aluminum heads, and either a 750cfm carb, or dual quads.

That engine could be duplicated for a little under half their price if you do the work, sans warranty.

Of course there's dozens of ways to make that kind of power, and prices all over the map to match. Using Huggers suggestion of Vortec heads (Great idea!) The Goodwrench quest article from the early 2000's has a GM Crate with Vortec heads making 384hp, 401ft-lbs torque. The corvette LT-1 heads make slightly less HP/TQ but also shave weight.
