A few weeks ago my engine bent a push rod while i was driving down the road and i want to know why it did that. I was driving down to road road like a normal person does and it starts to act like a spark plug wire came off so i managed to get it back to the mechanic and he said it had bent a push rod. So it was towed to the chevy place where it was installed at and they said that was not a engine defect and they tried to fix and they cannot get it right so i took it back to my regular mechanic and he is going to see what he can do monday. By the way it was a universal 350 that chevy sells. What is your opiinon on thsi engine? If i have to get a new engine i am going to get chevy's 383 truck engine.
