which alphabet cam

[sn95gt19]

i have the e cam, i didnt really notice any difference except, surging idle, and low vaccum. thats the one thing that i overlooked when building my motor. i had the b cam previously and that was a lot better except the power band was soo high, didnt really make power until 4200-rev limiter. but when it did get up high it pulled like crazy. i have heard a lot about the f cam, mostly good so i would say that or a trick flow cam.
