I was also shifting out @ about 6700 rpm's with the help of the Z06 hot cam valve springs. I had enough detonation to disenigrate both the ground strap & the electrode on the spark plug. as for me being certain of damage that occured, working here @ the dealership allowed me access to the infamous indoscopic bore scope. I am happy to report that not only did I not find any dimples in the pistons but I have no smoke, oil consumtion, or compression loss. Mike(tigerfan187) has a bent pushrod. I have looked at it & heard it as well.

Mike is not running lean, he dynoed around 12.8 last time with the wideband. He is running 28 degrees of total timing, compared to my 34 degrees. I am so certian that he bent a pushrod that I would be willing to bet large sums of money on it. but if I am wrong, I am wrong.

Now let's talk about these horrible things that flyer & richard are saying about me. I have never abused my vehicle in any way/shape/or form. This transmission issue(3 transmissions in 21,000 miles) is because gm has design issues. It has nothing to do with my 6800 rpm shifts. All joking aside if you guys worked here at a dealership, in the service department & had access to the tools & resources that I do, & was able to get it covered under warranty would you not thrash your vehicles if you suffered no finacial consequences.....

Flyer you are jealous of my bottle heater, I know you want it, but I have a patent on the design,

Richard you are jealous of my amazing speed, I think after work I will come by your house & pop a wheelie in my truck rain & all

Oh yeah mike, I whored up your thread again.......lol...lol

I highly doubt the valves are floating at 5700 rpm. what rpm did he pull on the dyno? any valve float there?

Once again I would really like to know what your function is in the service dept.

About the valve float, I've always seen stuff that says valve float is after 6200 rpms. You showed me that magazine ariticle that said a 5.3 revved really high (6400rpms+) on stock springs and a big cam and experienced NO VALVE FLOAT. Again, I'm no expert, just going by what I see and hear.
