Depends on rocker ratio, porting, intake and exhaust systems and other things about the details.
Generally a 350 with the LT4 HOT cam, 9.5 compression with 1.6 rockers, well ported Vortec heads, Edlebrock Performer RPM intake with a 750 Holley, and 1-3/4 inch long tube headers should pull in the range of 400 to 420 hp on an engine dyno.
