I don't know if I'm not getting the complete story here or what, but the approach to finding the problem doesn't make a lot of sense. From your description it seems like the answer to an rpm limit problem was to bore the block and rebuild the bottom end. In truth, even a piston with a very low compression/leakdown won't limit your rpm. What were the compression/leakdown numbers before you all decided to tear down the shortblock? And again, was the ecu showing any codes?

At the very least, I'd ask that you don't tell anyone that we said you should rebuild the engine because of an rpm problem - because we didn't! Thanks in advance...
