ok.....Since you dont have much converter, you need to be careful. You could prolly go with the crane you have listed above and still retain your converter. It will want to push your truck some at a stop light because you will be idling faster and such. You can also run the affordable 918 springs with that cam. An off the shelp cam will be fine for what you are wanting to do. You are not going to hear much cam with that one but it is going to make a ton of torque, should make your truck feel really good! Thats what your truck needs, ricers need HP. lol good luck with your swap!
