Mike,

In the 'Tech Tips' section of this site, under 'Cam Specs, 250" Series Engines', a listing of cams for the Chevrolet 194-230-250 engines is shown. This list should be very similar to those available for the Chevrolet 292 camshaft, which has the fuel pump lobe in a different location.

Other guys can add in here, for a street/strip cam, consider .050" duration in the 208 to 218 degree range.
