If you want a crate 350, the L31 Vortec is an excellent choice. You'll need an intake manifold and electric fuel pump, but you'll get a one-piece rear main seal, a roller cam, and the best-flowing heads GM ever produced for the SBC. It should be good for around 300 HP, but the usable torque curve is much broader than that 290 HP engine you're looking at.
