Any idea on your exhaust flow cfm #'s? If so, here's a reference that should get you in the ballpark size-wise:

This chart applies to normally aspirated engines. For street headers, where low-speed torque is of prime importance (especially with a stock converter and high rear end gears), use the lower line to select the appropriate primary size. For hot street machines having reasonably big cams and decent compression, use the middle line to size the primary. For race engines, use the top line.
