Your best bet is to call the tech line on any major cam manufacturer and give them the specs on your vehicle. They can narrow it down from there and tell you what your best option is for the type of driving you are going to do. Be prepared to know the vehicle weight, gear ratio, type of trans, converter stall speed, type of heads, compression ratio, etc. If it is an otherwise stock engine then just tell them what vehicle it is and they can go from there. This takes out all of the guess work and you end up with a better combo.
