Typically, a spring rate between 350 – 450 is used for small blocks and a spring rate between 450 – 550 is used for big blocks, but your particular circumstance may vary depending on factors such as aluminum versus cast iron componentry (heads, intakes, etc.), adding heavier engine components such as blowers, etc..  The chart below is meant as a reference guide only.  Your needs may vary.
