Possibly he installed the correct corvette valve covers on his vette engine . and it got over its hurt feelings and stated up? One time I had a old 6 cyl chevy one front tire was flat. I attempted to start it and flooded the engine. I told my Friend Jim it didn't start because the engine isn't level. So we jacked it up and took off the tire and patched it. That took long enough for the flooded engine to clear and it cranked right up. I had Jim believing that the unlevel condition was responsible for the no start when all it was my leaving the manual choke fully closed.
