kessler if you are new to this you need to read read read read read. check out the tech forums on here and other places like ls1tech.com. check out part reviews on vendor sights. let me tell ya, ur mind on what you want will change a hundred times before you are actually ready to do the work anyways at this stage so u might as well educate urself. asking questions is fine, but "what to do" is just too vague. there are guys running cams in the 224 range DD and guys running TREX cams just the same. the bigger cams can be harder to deal with and less downtown friendly, but it depends on what you can personally handle. if you are brand new promise yourself to stick to basic boltons for the time being and just start chatting with the guys around here. you will end up making much better use of your money than if you just start modding all willie nillie (or nimbly bimbly for our ST fans)
