I need to know if when your wanting to buy a camshaft what decides how big it is. i always hear people talking about how they have a 450 cam in somwthing what is that 450? i am goiing to put a bigger cam in my truck and need to know how to identify what is big and what is little. Also what are some stuff that i could do to build horses in a 350? obviously carb and intake and headers. Its already bored .40' over and has flattop pistons, its got 1.94" heads a high-rise intake a four-barrel and headers. What can I do to the valvetrain to improve performance and adda few ponies. Thanks
