LS 6's let go on a road course when red line is moved to 7000 rpm.
Check with Katech for rod bolts & info.
I don't know how the rod bolts hold up @ 7K rpm for drag racing... but our guys have had engines blow on the road courses...

I use to turn it 7000, but power felt like it fell of. I turned the limiter back to 6800 where it was for years. I installed a fast 90 and it seemed to carry power better up top to I turned it back up to 7000. It's mostly a street car. I have done a couple roadcoarses over the years but not much....atleast in my car.

thanks, i'm happy as well. this was an experiment and seems to be working. people rarely run this much comp in a 'stock' cam, but E85 is an awesome thing. it's also a torque monster with 1100nM (800+ft/lb) at the wheels when the convertor kicks in, good enough for 1.53 60ft in heavy commodore. although my diff didn't like it and my 4.11's shreaded 5 crown teeth ![Sad](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_sad.gif)

The flex plate broke and took out the starter and a piece of the tranny bell. No problem. Repaired the starter using parts from another bad one I had stored away. Ordering the flex plate today. Just don't feel like pulling the tranny. Oh well.
