Yes you are correct, these are Crane rockers. Does anyone have any info on these. they are supposed, for exsample, start at low lift- 1.79 ratio and then at mid lift revert back to 1.7 ratio to the maximum lift programmed by the Cam.
I'm thinking of installing this on a light cam for my Z06, which will have a lift of .551/.551.
Any thougths on this.

had them installed by VHP in the 99 formula. the 1.89 accelerated lift kit. http://www.stealthram.com/99formulatimeslip.html picked up almost a tenth and almost 1 mph. here's some info on the accelerated lift technology. http://www.vincihighperformance.com/...RTSPARENT.HTML
here are the dyno sheets. the tq peak is misleading. there was a spike at the beginning.

Mrr23,
What type of cam did you have with these pulls... The bottom dyno chart showed a huge jump in torque from 328 to 37X something.. Did you change a cam, if so what kind.
Could you feel this jump in power with the rockers.. Did these rockers affect you idle or streeability of the car. I'm looking at their 062 cam 210/218 .551/.551 lsa 112...

let me quote myself on the torque jump
it sometimes happens with automatic cars. the cam is stock 1999 LS1 cam. yes i did feel a difference with the rockers. more crisp throttle response. car accelerates way better with them. in an automatic you can feel how the LS1 doesn't have much low end response until about 2800 rpms. the rockers brought low end response up.
