to add to what was just stated above by readymix (which is good info, by the way), if you ever want answers to a question specific to your vehicle, you need to tell us what the heck it is. yeah, you said its a suburban - but in regard to your questions, knowing the kind of motor it has would be important. i suppose i could run down to the junk yard and get a nice 80's honda set of cams and mail them to you - $100 each. people do wierd stuff and put wierd things in their trucks sometimes.
