I want a different cam for my 393 Stroker in my 68 Stang. Currently i have a 280 Isky mega(.517 lift...232 duration @.050) with 10.2 to 1 Comp, World Windsor Sr. Heads, Perf. Rpm Int, and 750 Holley Vac Sec. I want a split profile cam that will increase my mileage a little and work with my 3.50 gears and 2400 stall. Any suggestions?
