340 horsepower

is it possible to squeeze 500-550 hp out of a j headed stock stroke 340 with say 11:1 compression, h beam rods,forged pistons and balanced rotating assembly. also maybe a solid roller and j heads that have been prepped to the max say from shady dell speedshop. i only want to keep j heads because of the visual factor of a sleeper like the rest of my car.

thanks
