65 is what's needed ..and no old man when I went to the 75 on the s/c car there was a gain of over 48hp. when I went with the 90mm and 80mm T/B another 35hp was on tap..now the restriction is in the intake-heads

plan for the future go with the 70, i have a 65 right now i'm i'm just bought ready to upgrade myself, 65 comes stock with the cobra so it does flow pretty well but with future mods in mind i would save your self some money now and get the 70mm
