I can see the logic and I'd agree in a perfect world. But having "been there and done that" I don't believe their are any reputable rebuilders and a warranty in most cases is a legal wrangling to get compensated for everything that goes along with a long block.. Like removal/installation, shipping, support parts (water pump, etc.). Mass rebuilders rebuild knowing it only needs to get past the warranty and the work and parts are simply mediocre at best. I never had seen some shady actions until I took apart mass rebuilder problem engines.
