Im about to rebuild my 2001 lb7 with 245000. Just starting to do the research on it and found this post to be very informative. To the gentelman that started this forum i am thinking on the same type of rebuild as you how much $ did all the material end up costing.
I think it ended up around $5500 after the extras (injectors, up pipes/manifolds) were factored in. I could have done the rebuild for around $3000 without those things
