5.7/6.1 hemi engine builders

your talking about part installs but how about true machine work. are local machine shops capable of doing the necessary boring ,decking, truing, aligning balancing,ect. or is this a dark area. i have never been one to just throw parts on any engine in any condition just to say i have a cam. i have to know what my clearances and tolerences are. i like a good blue print. for what ever budget build. who are the capable builders in the southeast, northeast, midwest,and so on. this is the kind of knowledge we need to help everyone, at least imo
