The heads are being put on now

Jerry, what do you suppose caused the pushrods to bend? You said you hit 7K, RPM by itself doesnt bend pushrods. Then the thread turned to chamber volumes(?) You bent pushrods because something collided, most likely a valve to piston. Has your LMS disassembled the heads and measured out your valves? If they havent suggested some further investigation about your bent pushrods I would be very concerned. Take the opportunity to look further..
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 .

Motherfuck , the mechanic showed me the wrong push rods !!! they were from another 340 , not mine , he made a mistake . Wow what a relief .
Going on the dyno in an hour or so , I'm off to see the test
