When we drove up to L.A. for the Brothers Show and Shine my engine bent a push rod as we were getting off the freeway about 4 miles from the event. Was a great show but a little bitter sweet as I spent the day contemplating the cost of towing 100 miles back home and rebuilding my GM crate motor with only 14,000 on it. I believe it was a seized valve guide that put too much pressure on the push rod, we will see.
