my 6x4s flow 252/217 which is 86%. and im running nitrous. so in my case a dual pattern would be better with more on the intake??? you dont see many advertised cams with more on the intake usually vise versa. the crower i wanted was 247int 252exh. with a 112LSA. with 1.65 rockers. some say the rockers will change the duration slightly is this true?
thanks- scott
