Calling on the solid cam experts here. I am working on a small block with a solid flat cam. The engine only has about 100 miles on it, engine was built and sat for about two years before turning on. It was generously lubricated during assembly but the FI system failed to start up successfully and went to carb. Once fired up engine was run at the recommended sustained over 2k rpm for 20 minutes. Once vehicle completed car was driven for roughly 100 miles and a tapping sound began. Valve lash checked and was found to be between .020-.023 (recommended was .010-.012) readjusted and oil changed. Noticed a lot of metal in the motor oil. High Zinc oil was used from beginning. Drove and noise went away but was concerned for the amount of metal in oil. Pulled motor out and disassembled. Confirmed lobe damage just not what I expected to see. Lifters all look perfect btw. Here are some pictures. TIA
