The always elusive CAM question..
I should of said early in the design process, first is purpose then to power to weigh ratio then powerband then engine size then cam and head combo then match gearing, intake,carb, compression etc... You should know your cam before machine works begun.
I just see lots on here saying something like I got a 3800lb car with 8.5:1cr, 2:73gear, stock stall, single plane, ported J heads, daily driver and want to sound like a race car which cam?
