Hurt the LT1 tonight.

[Matts94Z28]

Well looks like the LT1 is hurt after tonight. I ended up making two passes before it went down. On the last pass the car held on to second gear and wrapped up pretty high, 7k or so, so I had to get out of it way before the traps. Car went 7.92 @82 w/ a 1.81 60ft... went to crank it up and heard a bunch of chatter under the passanger VC. We towed the car home and I pulled the valve cover off expecting to find a broken rocker, stud or valve spring... to my suprise they were fine!

I just cant figure out what the noise could be... it doesnt sound like a lifter and the pushrods are not bent. I am wondering if I could have floated the valves and bent one. Then again I have a TON of PTVC considering I run -5cc flat tops and the pistons are still in the hole some (not zero decked).

Any thoughts on what it could be? Here is a video of the noise, you can hear it best in the last ten seconds of the video. http://www.youtube.com/watch?v=uuLkhZVQacs


Big thanks to Robert, Zac and Brandon for all the help tonight! If it wasn't for those guys I would not have gotte the car home...

Ohhh and thanks to Darryl for getting me lined up! I hooked up well and kinda wish I would have gotten on the converter more... a 1.6 would have been nice to see.
