For those of you that have done your own builds, have you used your stock block or do you get a new one and why? What is the list of parts needed to go built? Such as cam gears and such ( not the stuff for the internals of the short block ) Im thinking of going built and I have the money, just not sure of what way to go in terms of how/who does it. I was going to just go with a KB but since that deal fell off AGAIN im thinking of just going built.
