Here is what I came up with . 298.8 H.P at 4200 RPM's and 413.1 Ftlbs at 3000 RPM's . If your Looking for max H.P . That Camshaft is on the Small Side . Yes the 1.60 Rockers would Help this Build make more Power . But all and all it's not a Bad Street car Engine . Dial in that 600 Holley and HEI and you will Like it .
