Yes for a 350+60 Over 360ci maybe 12.1 C/R Build that is making Good Power . Your Camshaft Lift is not so High it's that .050 Duration . You get to that Point with Stock casting Heads even ported . That they can only Flow So much . And this is a 360 Not a 383-406 . With 195cc AFR Heads or world Sportsman 200cc and the Bigger Cam the Power will Follow .
