It's strange for sure , everything looks great , nothing looks like there was a collision , valves , pistons all look perfect . The only thing I remember is it made a bit of noise at the end of the 7000 + rpm run and the car was lacking on the top end after that ,. I thought the cam went bad . I'll search some more once it's apart , but so far besides the bent rods nothing shows . 3 have a bit of a warp not that bad 1 is really noticeable , i saw it was bent just holding it , on the table it would not roll without a big push . I'll try to get pics of how bent the one is really bad .
