There a guy on here (shbox.com) some of you may know him with instructions for adjusting the rockers. I tries this and it took 2 full turns loosening on most to get them to clack. I then tightened them till it stopped. This happened with 1/8" each time so it tightened them 1/4 turn. Is it normal for them to need 2+ turns for this to happen. I just did one side so will i see a big difference in the cars performance?

"Some like to adjust the rockers while the car is idling. If you wish to do this, loosen one rocker at a time until you can hear it click. Tighten the nut, but don't exert downward pressure on the rocker arm with your socket. At the point when audible clicking is gone, tighten the nut another 1/4 turn for your preload"

 

Could them being to tight have been what caused my performance to be down so much? I am running 13.9's in the 1/4 and i am told by others that 12's would be more like it for my setup.

 

Yes if you have them to tight you are definatley loosing some power, I adjust my rockers with that car running as well. Just loosen the rockers till they start clanking then slowly tighten till the clacking stops (zero lash), then you want to adjust the preload depending on what type of lifter you have. I have the ls7 lifters and its usually about 1/2 turn preload.

 

I used shbox's #1 method with car OFF. very easy. never had and issues. 1.6 rockers LT4 springs, 1/2 turn preload.

Here's my writeup and a vid. hope it helps.

and i was told too tight will compress the lifters to the point where the valve won't fully close during firing, which is bad for power.

 

The passenger side took 2 to 3 full turns for most before it made the clacking when i loosened them. I noticed that both sides are very quiet with the covers off and all seems good. I now have a serious traction issue since the car has more power so i'll have to get used to that. I tried a few 0-60 runs and everytime i spun the tires for a few seconds but my times where still better than before. It time for some slicks and some track time. Thanks for all your guys help!

 

Haha thats good to hear mrmint, glad it worked out for you!
